Question

Calculate the molarity of pure water density of 1g/ml

Answer 1

Molarity is no of moles per litre.1g/ml density means that 1L (=1000 ml) weighs 1000g. So one litre of water has 55.55 mol water, and so molarity if water is 55.55 molar.

Answer 2

Answer:

Explanation:

Desity of water = 1 g mL-1

Mass of 1000 ml of water = V xd

 = 1000 mL x 1 gm-1

= 1000 g

 Moles of water 1000/18= 55.55 mol

Now, mole of H2 O present in 1000 mL or 1 L of water.

 So, molarity = 55.55M
