0.467 moles of H_2SO_4 are present in a sample of 45.8g of H_2SO_4

Explanation:

According to avogadro's law, 1 mole of every substance occupies 22.4 L at STP and contains avogadro's number 6.023\times 10^{23} of particles.

To calculate the moles, we use the equation:

\text{Number of moles}=\frac{\text{Given mass}}{\text {Molar mass}}

\text{Number of moles of} H_2SO_4=\frac{45.8g}{98g/mol}=0.467moles
