Question

Sea water contains 53 ppm of na2co3 . find mass of na2co3 present in water. assume volume of glass to be 250ml and the density of h2o to be 1g/ml.

Answer 1

Answer:

The given question is incomplete. the complete question is :

Sea water contains 53 ppm of Na2Co3 . Find mass of Na2Co3 present in 100 g of water.

The mass of  present in water is  

Explanation:

Concentration in ppm =

Given ; Concentration in ppm = 53

mass of solute  = x g  

Mass of solution = mass of solute   + mass of water = x g + 100 g

Thus the mass of  present in water is
