Question

Calculate the no of molecules drop of water weighing on.o48gm

Answer 1

Answer:

Molecular mass of water = 18 g

The number of moles of water=n=

Molecular wt.

weight

=

18

0.05

=2.78×10

−3

Now, number of molecules of water=n×6.022×10

23

=2.78×10

−3

×6.022×10

23

=1.67×10

21

molecules

Explanation:

This is not the answer but these is similar to this just change the weight.
