Answer:

= 62g

Explanation:

We have been asked to find the mass of Na2O having 6.02 x 10^23 units.

We know that one mole of a substance contains 6.02 x10^23 units/particles.

That means we have one mole of Na2O.

To find the mass of Na2O we use the formula,

mass = number of moles x formula mass

= 1 mole x 62g/mol

= 62g

Therefore the mass of Na2O with 6.02 x 10^23 units is 62g.
