Question

The number of atoms present in two molecules of Sodium hydroxide is

Answer 1

Answer:

of moles of sodium hydroxide [NaOH] contained in 160 g of it is:(Molecular Weight Na = 23, O = 16, H = 1 g/mole)

...

No. Compound (Mol. wt.) Weight (in g)

III H2O2 (34) 6.8

IV SO2 (64) 1.6

Answer 2

Explanation:

No. of atoms in 1 mole of NaOH = N

A

=6.02×10

23

∴ No. of atoms in 0.01 moles of NaOH = 6.02×10

23

×0.01=6.02×10

21
