1.	A solution is prepared by adding 2 g of a substance A to 18 g of water. calculate the mass per cent of the solute.
Answer» -• MASS of SOLUTE, A = 2 g.• Mass of solvent (water) = 18 gTo Find :-• Mass % of solute, A Solution :-At FIRST, we NEED to find mass of solution. Mass of solution = Mass of solute + Mass of solvent = 2 g + 18 g= 20 g━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
