Question

1. calculate the molar mass of carbon dioxide (co₂).

60.0 g/mol
44.0 g/mol
28.0 g/mol
32.0 g/mol
clear all

Explanation:

Step1: Find atomic masses

Carbon (C) atomic mass: $12.0\ \text{g/mol}$, Oxygen (O) atomic mass: $16.0\ \text{g/mol}$.

Step2: Calculate molar mass of $\text{CO}_2$

$\text{CO}_2$ has 1 C and 2 O. Molar mass = $12.0 + 2\times16.0 = 12.0 + 32.0 = 44.0\ \text{g/mol}$.

Answer:

44.0 g/mol (the option with "44.0 g/mol")
