Question

Calculate mass of 3.011×10^23 molecules of SO4​

Answer 1

Answer:

The mass of $(3.011\times10^{23}\text{ molecules})$ of $\text{SO}_4$ weighs 48 gm.

Explanation:

Molecular mass of $\text{SO}_4$ is 96 gm.

Therefore, 1 mole $(6.022\times10^{23}\text{ molecules})$ of $\text{SO}_4$ weighs 96 gm.

Therefore, $(3.011\times10^{23}\text{ molecules})$ of $\text{SO}_4$ weighs 48 gm.
