🤓 Based on our data, we think this question is relevant for Professor Cavanaugh's class at San Diego Mesa College.
We are asked to calculate for the mass percent (mass %) of Cl in HCl.
To do that we’re going to use the mass percent formula shown below:
First, we need to get the molar mass of HCl.
Molar mass of HCl:
HCl 1 H x 1 g/mol H = 1.00 g/mol H
1 Cl x 35 g/mol Cl = 35.45 g/mol Cl
Sum = 36.45 g/mol HCl
What is the mass percent of chlorine in hydrochloric acid?
