Question

How much mass of S is present in 1.5×10^22 molecules of H2SO4

Answer 1

Molar mass of H2SO4 =98g

molecules=1.5×10^22

formula---:

$\frac{given \: mass}{molar \: mass} = \frac{molecules}{avogadro \: number } \\ \frac{given \: mass}{98} = \frac{1.5 \times {10}^{22} }{6.022 \times {10}^{23} }$

I am not confirm the process but you are solve the answer by teacher.
