Question

Calculate the number of moles in 9.8 g of sulfuric acid (H2SO4).

Answer 1

Answer:

Number of moles = 0.1

Explanation:

Given mass = 9.8 g

Now, we havevto calculate molar mass.

Molar mass of sulphuric acid (H2SO4)

= 2×1 + 1×32 + 4×16 = 2 + 32 + 64 = 98 g per mol

Now,

$Number \: \: \: of \: \: \: moles \\ = \frac{Given \: \: \: mass}{Molar \: \: \: mass}$

$= \frac{9.8}{98} = \frac{98}{98 \times 10} = \frac{1}{10} = 0.1$
