Question

A sample of 45.8g of H2SO4

contains how many moles of H2O4

?

Answer 1

Your answer is 45.8/98=0.47 moles.

Answer 2

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:

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

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