Question

Calculate the number of atoms present in one litre
of water (density of water is 1 g/mL).
(1) 16 N
(2) 166.5 N.
(3) 1.665 N
(4) 1665 N
please reply answer​

Answer 1

Explanation:

In 1L of water 1000ml will be.

then 1000g also will.

and the number of moles = 1000/18= 55.55 moles.

in 1 mole

$6.022 \times {10}^{22}$

hence number of molecules will be.

55.55×6.022×10^22

354.55×10^22 = 3.54×10^24 molecules of h2o
