Answer:
The answer to your question is 1.6 moles of H₂SO₄
Explanation:
Data
moles of H₂SO₄ = ?
mass of H₂SO₄ = 157 g
Process
1.- Calculate the molar mass of H₂SO₄
Molar mass = (1 x 2) + (32 x 1) + (16 x 4)
= 2 + 32 + 64
= 98 g
2.- Use proportions and cross multiplication to find the moles of H₂SO₄
98 g of H₂SO₄ -------------- 1 mol
157 g of H₂SO₄ --------------- x
x = (157 x 1) / 98
x = 157 / 98
-Result
x = 1.6 moles of H₂SO₄
