Question

calculate the molarity of pure water​

Answer 1

Answer:,

Molarity is basically the number of moles present per unit volume of the solution. But we'll go into fully detailed method. The density of pure water is 1000g/L and its molar mass is 18.02 grams per mole. Therefore, the molar concentration of water is 1000 g/L÷18.02 g/mole = 55.5 moles/L.

Answer 2

$\large\underline\mathrm\red{Solution}$

• The density to be 1 one litre of water weights 1000 gram or 1000/18 moles. $\large\mathrm\red{( H2O \: \: = \: 18)}$.

$\large\mathrm\red{Molarity:-}$

$\implies$ 1000/18

$\implies$ 55.55 M $\large\mathrm\red{(moles/liter)}$
