One mole is the amount of substance that contains as many elementary particles as 12 g of _^12C isotope of carbon. Calculate the number of moles in 1 litre of water ("Density of water is "lg//mL). Also calculate the number of water molecules in 1 litre of water

Answer»

Solution :NUMBER of moles = `"MASS of the substance"/"GRAM molecular mass"`Number of moles in LITRE of water =`(1000g)/(18g)=55.55` Number of water molecules in litre =`55.55xx6.022xx10^23=334.5xx10^23=3.345xx10^25`
