How many moles of H3PO4 are contained in 150.0 mL of 18.1 M H3PO4?

Answers

Answer 1

Answer:

Number of moles = 2.72 mol

Explanation:

Given data:

Number of moles of H₃PO₄ present = ?

Molarity of solution = 18.1 M

Volume of solution = 150.0 mL (150/1000 = 0.15 L)

Solution:

Molarity is used to describe the concentration of solution. It tells how many moles are dissolve in per litter of solution.

Formula:

Molarity = number of moles of solute / L of solution

By putting values,

18.1 M = number of moles / 0.15 L

Number of miles = 18.1 M × 0.15 L

Number of moles = 2.72 mol
