Question

If 0.85g of NH3 is dissolved in 100ml of solution find molality if density of solution is 1.2g/ml
​

Answer 1

I am attaching a pic of all formulae of molarity and molality then adter learning those formula u must solve this question yourself

M = molarity

m = molality

x1 = mole fraction of solute

x2 = mole fraction of solvent

n1 = moles of solute

n2 = moles of solvent

m1 = molar mass of solute

m2 = molar mass of solvent
