Question

Using the principle of constant proportions, if there were 4 grams of Mg²⁺ in a seawater sample, how many grams of Na⁺ would be present? Show your work.

Answer 1

Answer #1

In normal Sea water the concentration of Na+, and Mg2+ is 10.7, 1.3 grams/ 1000 gram respectively

So their relative proportion is 10.7/1.3= 8.23:1

Now the principle of constant proportion says ,that the internal proportion of different salt remainsn remains same

So if magnesium is 4 gram the Na+ should be

4× 8.23= 32.92 grams of Na+ approximately.
