Hello,

To find the number of moles of sulfuric acid (H2SO4), use the formula:

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

The molar mass of sulfuric acidacid h2SO4) is approximately 98 g/mol. Given that 0.49 g of sulfuric acid is provided:

\text{Number of moles} = \frac{0.49}{98} \approx 0.005 \, \text{moles}

\]

So, the number of moles of sulfuric acid is approximately 0.005 moles.

Hope this helps you,

Thank you
