Answer:

1.536×10^23

Explanation:

One mole of any compound has N molecules.

Where N is the Avogadro's number

Molecular weight of H2SO4 is

H2 = 2

SO4 = 96

H2SO4 = 2+96

98g/mol

Hence the number of mole of H2SO4 in 25g = 25/98 = 0.2551mol

Number of molecules = 25/98 × 6.022×10^23

= 1.536×10^23 molecules

The number of molecules there are in 25g of H2SO4 is; 1.536 × 10²³.

According to Avogadro's law and Avogadro's constant;

One mole of any compound has 6.022 × 10²³ molecules.

We must determine the molecular weight of H2SO4 as follows;

  • H2 = 2

  • SO4 = 96

  • H2SO4 = 2+96

molar mass = 98g/mol

Consequently,

  • The number of mole of H2SO4 in 25g = 25/98 = 0.2551mol

The Number of molecules in 25g of H2SO4 = 0.2551 × 6.022×10²³

= 1.536×10²³ molecules
