How many moles are in 5.5 x 10-23 molecules of H2O

0.914moles

Explanation:

The number of moles in a substance can be got by dividing the number of atoms/molecules/particles by Avagadro's constant (6.02 × 10^23).

That is;

number of moles (n) = number of atom (nA) ÷ 6.02 × 10^23

According to this question, there are 5.5 x 10-23 molecules of H2O

n = 5.5 x 10^23 ÷ 6.02 × 10^23

n = 0.914 × 10^(23-23)

n = 0.914 × 10^0

n = 0.914 × 1

n = 0.914moles

1. contrast, 2. movement,

Explanation:

IN Paul Delaroche's The Young Martyr, He used the principles contrast, and movement. An example of contrast in The Young Martyr is the fact that the lady is shining bright among the dark river. An example of movement is the water is moving with a chill speed. by following the waves, you can see the water flowing around her.
