Question

How many moles of HBr would be in an HBr solition with a 6.0 molarity and 3.0L od H2O solvent?

Answer 1

Answer:

Number of moles of HBr = 18 moles

Explanation:

Given data:

Molarity of HBr = 6.0 M

Volume of solution = 3.0 L

Number of moles = ?

Solution:

Molarity = number of moles / volume in litter

number of moles of HBr = Molarity × volume in litter

number of moles of HBr = 6.0 moles/L ×  3.0 L

number of moles of HBr = 18 moles
