33 grams
Explanation:
CO2 is the chemical formula of carbon dioxide.
Given that:
Amount of moles of CO2 (n) = 0.75
Mass of CO2 in grams = ?
Obtain molar mass of CO2 using the atomic masses of the individual elements
Carbon = 12g; O = 16g
CO2 = [12g + (16g x 2)
= 12g + 32g
= 44 g/mol
Since, n = mass in grams / molar mass
0.75 moles = mass in grams / 44g/mol
mass in grams = 0.75 moles x 44g/mol
mass in grams = 33
Thus, the mass of 0.75 moles of CO2 is 33 grams
