Question

How much HCl exists in 347 mL of 0.48 M solution of HCI? Answer in units of mol.

Answer 1

Answer:

Number of moles of HCl = 0.17 mol

Explanation:

Given data:

Volume of solution = 347 mL

Molarity of solution = 0.48 M

Number of moles of HCl present = ?

Solution:

Formula:

Molarity = number of moles of HCl / volume in L

Volume in L:

347 mL× 1L / 1000 mL

0.347 L

by putting values in formula:

0.48 mol/L = number of moles / 0.347 L

Number of moles = 0.48 mol/L × 0.347 L

Number of moles = 0.17 mol
