l of gas occupies 22.4 liters. Steps to Solve Matter Mole Problems Identify What the Problem Asks For Read the problem carefully to determine the unknown quantity—be it mass, moles, particles, or volume. List Known Values Write down known quantities and relevant data such as molar mass, given
n gas reacts with excess oxygen according to the reaction: \[ 2H_2 + O_2 \rightarrow 2H_2O \] Solution: Step 1: Write the molar masses: \( H_2 \): 2.02 g/mol \( H_2O \): 18.02 g/mol Step 2: Convert known mass of \( H_2 \) to moles: \[ \text{moles of } H_2 = \frac{10.0 \text{ g}}{2.0
