Question

How many grams of CO2 are in 4 mol of the compound?

Answer 1

Answer: 176.04 g

Explanation:

Data:

1) compound CO2
2) n = 4 mol
3) mass in grams = ?

Formula:

mass in grams = n * molar mass

Solution:

molar mass of CO2 = 1 * atomic mass of C + 2 * atomis mass of O

atomic mass of C = 12.01 g/mol
atomic mass of O = 16.00 g/mol

molar mass of CO2 = 1 * 12.01 g/mol + 2 * 16.00 g/mol = 44.01 g/mol

mass in grams = 4 mol * 44.01 g/mol = 176.04 g

Answer: 176.04 g
