# How do you convert 4.25 xx 10^-2 mol H_2SO_4 to molecules H_2SO_4?

$\text{Multiply by Avogadro's number} , {N}_{A}$
${N}_{A} = 6.022 \times {10}^{23} \cdot m o {l}^{-} 1$
And thus $4.25 \times {10}^{-} 2 \cdot m o l$ of sulphuric acid represents $4.25 \times {10}^{-} 3 \cdot m o l \times {N}_{A} = 4.25 \times {10}^{-} 3 m o l \times 6.22 \times {10}^{23} \cdot m o {l}^{-} 1 = 2.56 \times {10}^{21}$ molecules of sulfuric acid. How many moles of hydrogen, and oxygen do this molar quantity represent?
