M = 233g
M = 24 + 28+ 16 * 3 = 100g/mol
n = m/M = 233g / 100 g/mol = 2,33mol
Explanation:
number of mole s of H
2
= 0.25 moles
number of molecules = moles * Avogadro’s Number
number of molecules = 0.25×(6.022×10
23
)
number of molecules = 1.505×10
23
single molecule of hydrogen contains two H-atoms. So,
number of atoms = 2×(1.505×10
23
) = 3.01×10

Using evidence to support explanations is a good practice because it proves that what you are explaining can be verified.
