Question

How many ATOMS in a `49*g` mass of sulfuric acid?

Answer 1

Approx. `2.1xx10^24` individual atoms.................

Explanation:

We know that in the ONE MOLECULE, the ONE FORMULA UNIT of sulfuric acid, there are 7 atoms: `4xxO;2xxH`; `1xxS`.

We also that know that in a molar quantity of sulfuric acid, i.e. a `98.08*g` mass there are `N_A` individual formula units, where `N_A="Avocado's number"=6.022xx10^23*mol^-1`.

And thus number of atoms, `="7"*"atoms"xx(49*g)/(98.08*g*mol^-1)xx6.022xx10^23*mol^-1=??"atoms....."`
