Question

question 3 (5 points) what is the mass of 0.360 mol of hcl? a) 0.360 g b) 13.1 g c) 101 g d) 2.17 1023 g

Explanation:

Step1: Find molar mass of HCl

Molar mass of H is $1.008\ \text{g/mol}$, Cl is $35.45\ \text{g/mol}$. So molar mass of HCl is $1.008 + 35.45 = 36.458\ \text{g/mol}$.

Step2: Calculate mass using $m = n \times M$

Given $n = 0.360\ \text{mol}$, $M = 36.458\ \text{g/mol}$. So $m = 0.360\ \text{mol} \times 36.458\ \text{g/mol} \approx 13.1\ \text{g}$.

Answer:

b) 13.1 g
