Question

How many grams are in 3.45 moles of CO2?
​

Answer 1

To find grams from moles, multiply moles by molar mass of CO2,
The molar mass of CO2 is 12.01+32=44.01g CO2
Multiply 3.45 mol*44.01 and you will get 151.8g CO2

Answer 2

The weight of 3.45 moles of carbon dioxide has been 151.8 grams.

Moles can be calculated as the mass of solute present with respect to the molecular mass of the solute.

Moles can be expressed as:

Moles = \rm \dfrac{weight}{molecular\;weight}

molecularweight

weight

The molecular weight of carbon dioxide has been 44 grams/mol.

The given moles of carbon dioxide = 3.45 moles.

3.45 mol = \rm \dfrac{weight}{44\;g/mol}

44g/mol

weight

Weight of carbon dioxide = 3.45 \times× 44 grams

Weight of carbon dioxide = 151.8 grams.

The weight of 3.45 moles of carbon dioxide has been 151.8 grams.
