Calculate the mass of each of the following: 7 moles of sulphuric acid

1.	Calculate the mass of each of the following: 7 moles of sulphuric acid
Answer» Given: Number of moles = 7 Atomic mass of H₂SO₄ = 2 ×1 + 32 + 4 × 16 = 98g/mol To find out the mass of sulphuric acid, apply the formula given: Number of moles = \(\frac{Mass}{Molar\,mass}\) ⇒ 7 =\(\frac{mass}{98\,g/mol}\) ⇒ Mass = 7 mol × 98g/mol ⇒ Mass = 686g Thus, the mass of sulphuric acid is 686g.

Answer»

Given:

Number of moles = 7

Atomic mass of H₂SO₄ = 2 ×1 + 32 + 4 × 16 = 98g/mol

To find out the mass of sulphuric acid, apply the formula given:

Number of moles = \(\frac{Mass}{Molar\,mass}\)

⇒ 7 =\(\frac{mass}{98\,g/mol}\)

⇒ Mass = 7 mol × 98g/mol

⇒ Mass = 686g

Thus, the mass of sulphuric acid is 686g.
