Answer 1

One mole of Na2SO4 10H 20 is dissolved in 820 grams of water to make a solution. What is the + molality of Nations in the resulting solution? [Atomic mass (u): H = 1, O = 16, Na = 23, S = 32) answer me

One mole of Na2SO4 10H 20 is dissolved in 820 grams of water to make a solution .

Atomic mass (u): H = 1, O = 16, Na = 23, S = 32)

What is the + molality of Nations in the resulting solution .

Molality = No of mole of solute / Weight of solvent × 1000

So the answer is 1.21
