Question

The molar mass of CO2 is 44.01 g/mole. Choose which of the following correctly represents this relationship correctly as a conversion factor. 1 mol CO2 = 44.01 g CO2 44.01 mol CO2 = 1 g CO2 44.01 molecules CO2 = 1 g CO2 1 molecule CO2 = 44.01 g CO2

Answer 1

Answer : The correct option is, $1molCO_2=44.01gCO_2$

Explanation :

Molar mass : It is defined as the mass of the substance in grams or kilograms present in the one mole of substance.

The unit of molar mass is, gram/mole or g/mol.

Given : Molar mass of $CO_2$ = 44.01 g/mole

That means, one mole of $CO_2$ contains 44.01 gram of $CO_2$.

Answer 2

Answer:

The correct answer is : 1 mol of $CO_2$ = 44.01 grams of $CO_2$.

Explanation:

Molar mass is defined as the sum of the mass of all the atoms each multiplied its atomic masses that are present in the molecular formula of a compound. It is expressed in g/mol.

$n=\frac{m}{M}$

n = moles of compound

m = Mass of the compound

M = Molar mass of the compound

We are given with molar mass of carbon dioxide gas which is 44.01 g/mol.

The means that mass of the 1 mole of carbon dioxide gas is 44.01 grams.

n = 1 mole, m =?, M = 44.01 g/mol

$n=\frac{m}{M}$

$m=n\times M=1 mol\times 44.01 g/mol=44.01 g$

So , relationship between molar mass and mass of the carbon dioxide is given as:

1 mol of $CO_2$ = 44.01 grams of $CO_2$
