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

Answer:

What is the question needing to be answered?

Explanation:

Usually with a scientific hypothesis, you ask the question in an if, then statement. For example: If it rains outside, then the ground will be wet. It's kind of like a cause and effect statement.
