Question

how many moles of water are present in 1 litre of water

Answer 1

55.55 Moles

Given:

1 Litre of Water

To Find:

Number of moles that are present in 1 Litre of water.

Converting 1 Litre to Ml by multiplying by 1000:

= 1 x 1000

= 1000 mL

Calculating the molar mass of water:

(H2O)

= 1 x 2 + 16 x 1

= 2 + 16

= 18

Formula used to calculate the number of moles:

Weight of water in mL / Molar Mass of water

Substituting all the values known to us in this formula we get:

= 1000 / 18

= 55.55 Moles

Therefore, 1 Litre of water has 55.55 Moles.

Answer 2

1 liter = 1000 ml

Water = 1*2 + 1*16 = 18 ml

No.of Moles = 1000/18 = 55.55 moles
