convert from grams to moles for 36g CO2

Answers

Answer 1

Answer:

0.82 moles CO₂

Explanation:

To convert from grams to moles, you need to find the molar mass of CO₂. This conversion is a ratio stating the amount of grams CO₂ per 1 mole. The molar mass is calculated using the molar mass of each element (in CO₂) from the periodic table.

Molar Mass (Carbon): 12.011 g/mol

Molar Mass (Oxygen): 15.998 g/mol

Molar Mass (CO₂): 12.011 g/mol + 2(15.998 g/mol)

Molar Mass (CO₂): 44.007 g/mol

36 grams CO₂               1 mole
----------------------  x  --------------------------  = 0.82 moles CO₂
                                 44.007 grams

The statements describe a spring at its equilibrium position is the elastic potential energy is zero, the displacement of the spring is at a maximum and the net force acting on the spring is zero.

What is the equilibrium position?

A body is in equilibrium when the sum of all forces acting on it equals zero. According to Newton's First Law, when resulting from the laws that act on a body that remains in a state of restriction or in motion in its motion, it remains uniformly null.

In this case the only statements that match the definition of equilibrium position are:

A certain chemical reaction telesales 24.7 kk/g of heat for each gram of reactant consumed

Answers

The mass of reactant that would produce 800 Joules of heat is equal to 800 J × (1 kJ/1000 J)/(24.7 kJ/g).

How to calculate the mass of reactant?

In order to determine the mass of reactant that would produce 800 Joules of heat, we would set up a conversion equation as follows:

Note: 1 kJ is equal to 1000 Joules.

Conversion:

1 gram = 24.7 kJ

X gram = 800 Joules

Therefore, the mass of reactant that would produce 800 Joules of heat is given by:

Mass = Heat × (conversion factor/rate of heat)

Mass = 800 J × (1 kJ/1000 J)/(24.7 kJ/g).

How many grams of Ca(OH)2 are needed to produce 500 ml of 1.66 M Ca(OH)2 solution?

Answers

61.5 grams of Ca(OH)2 are needed to produce 500 ml of 1.66 M Ca(OH)2 solution. Details about mass can be found below.

How to calculate mass?

The mass of a substance can be calculated by multiplying the number

of moles of the substance by its molar mass.

However, in this question, the number of moles in 500 ml of 1.66 M Ca(OH)2 solution must be calculated first.

no of moles = 1.66M × 0.5L

no of moles = 0.83moles

molar mass of Ca(OH)2 = 74.093 g/mol

mass of Ca(OH)2 = 74.093 × 0.83 = 61.5g

Therefore, 61.5 grams of Ca(OH)2 are needed to produce 500 ml of 1.66 M Ca(OH)2 solution.

The enthalpy change, ΔH, of the reaction given below:

[tex]S_{(s)} + O_{2}_{(g)} \rightarrow SO_{2}_{(g)}[/tex]

The enthalpy change is calculated from the intermediate reactions:

[tex]S_{(s)} + \frac{3}{2}\:O_{2}_{(g)} \rightarrow SO_{3}_{(g)} \:\Delta H_{1} = -395.2 \:kJ\\SO_{3}_{(g)}\rightarrow SO_{2}{(g)} + \frac{1}{2}O_{2}_{(g)} \:\Delta H_{2} = 198.2\:kJ[/tex]

48g of 02 produce how many grams of Al2O3

Answers

Taking into account the reaction stoichiometry,  102 grams of Al₂O₃ are formed when 48 grams of O₂ react.

Reaction stoichiometry

In first place, the balanced reaction is:

4 Al + 3 O₂  → 2 Al₂O₃

By reaction stoichiometry (that is, the relationship between the amount of reagents and products in a chemical reaction), the following amounts of moles of each compound participate in the reaction:

Al: 4 moles O₂: 3 molesAl₂O₃: 2 moles

The molar mass of the compounds is:

Al: 27 g/moleO₂: 32 g/moleAl₂O₃: 102 g/mole

Then, by reaction stoichiometry, the following mass quantities of each compound participate in the reaction:

Al: 4 moles ×27 g/mole= 108 gramsO₂: 3 moles ×32 g/mole= 96 gramsAl₂O₃: 2 moles ×102 g/mole= 204 grams

Mass of Al₂O₃ formed

The following rule of three can be applied: if by reaction stoichiometry 96 grams of O₂ form 204 grams of Al₂O₃, 48 grams of O₂ form how much mass of Al₂O₃?

[tex]mass of Al_{2} O_{3} =\frac{48 grams of O_{2} x204 grams of Al_{2} O_{3}}{96 grams of O_{2}}[/tex]

mass of Al₂O₃= 102 grams

Finally, 102 grams of Al₂O₃ are formed when 48 grams of O₂ react.

What is the theoretical yield of Br2 for this reaction? Round your answer to the nearest gram.

Answers

After Rounding off The percentage yield is 64%

What is Percentage Yield ?

It is the ratio of actual yield to theoretical yield multiplied by 100% .

It is given in the question

20.0 g of bromic acid, HBrO3, is reacted with excess HBr.

The reaction is

HBrO₃ (aq) + 5 HBr (aq) → 3 H₂O (l) + 3 Br₂ (aq)

Actual yield = 47.3 grams

Molecular weight of Bromic Acid is 128.91 gram

Moles of Bromic Acid = 20/128.91 = 0.155 mole

Mole fraction ratio of Bromic Acid to Bromine is 1 :3

Therefore for 0.155 mole of Bromic Acid 3 * 0.155 = 0.465 mole of Bromine is produced.

1 mole of Bromine = 159.8 grams of Bromine

0.465 of Bromine = 74.31 grams of Bromine

Percentage Yield = (47.3/74.31)*100 = 63.65 %
