Question

find the # of moles in each

1. 300 g of $\text{h}_2\text{so}_4$

Explanation:

Step1: Calculate molar mass of $\text{H}_2\text{SO}_4$

Molar mass = $2\times1.008 + 32.07 + 4\times16.00 = 98.086\ \text{g/mol}$

Step2: Moles = mass / molar mass

$\text{Moles of }\text{H}_2\text{SO}_4 = \frac{300}{98.086}$

Answer:

Approximately $3.06$ moles (or exactly $\frac{300}{98.086}$ moles)
