Question

In a sample of 34.6g of H2SO4. How many moles are present?

Answer 1

Number of moles = 0.35 mol

Step-by-step explanation:

Given data:

Mass of H₂SO₄ = 34.6 g

Number of moles = ?

Solution:

Formula:

Number of moles = mass/molar mass

Molar mass of H₂SO₄ = 98.1 g/mol

by putting values,

Number of moles = 34.6 g/ 98.1 g/mol

Number of moles = 0.35 mol
