Sample Problem 3.12
Calculating the Molarity of a Solution
PROBLEM:
Hydrobromic acid (HBr) is a solution of hydrogen bromide gas in water. Calculate the molarity of a hydrobromic acid solution if 455 mL contains 1.80 moles of hydrogen bromide.
mol of HBr
concentration (mol/mL) HBr
molarity (mol/L) HBr
SOLUTION:
divide by volume
103 mL = 1L
= 3.96 M
