# How many grams are there in 1.5 x 10^25 molecules of CO_2?

Jan 28, 2017

$\text{Mass = no. of molecules / 6.023 * 10^ 23 * Molar mass}$

#### Explanation:

Molar mass of CO2 = 44g/mol

1.5 * 10^25 / 6.023 * 10^23" = 51.5 moles of CO2

$51.5 \cdot \text{44g/mol} = 2266 g r a m s$

Hope this helped
