What mass of znco3 contains 3.11×1022 o atoms

The molecular formula of the compound is , from the molecular formula it is clear that 1 mol of contains 3 mol of oxygen.

Also, in 1 mol there are atoms thus, 3 mol of oxygen will have atoms of oxygen.

Thus, there are atoms of oxygen present in 1 mol of .

1 atom of oxygen will be there in mol.

Number of oxygen atoms given is thus, this will be present in of .

Molar mass of is 125.388 g/mol, thus, mass can be calculated as follows:

Rearranging the above equation,

Putting the values,

Therefore, the mass of  is 2.16 g.

the earth would become to overheated and everything alive on it will eventually die from overheating. plants will eventually die as well, water will evaporate, and it will be nothing but a hot planet without anything living on it.
