% by mass is the mass of the solute divide by the total mass of solution times 100%. Or put another way, % by mass = mass solute/total mass of soln (x100%).Mass solute = 4.35 g
Mass of solution = 4.35 g + 105 g = 109.35 g (assuming a density of 1g/ml for water)
% NaCl by mass = 4.35 g/109.35 g (x100%) = 3.98 % (to 3 significant figures)

Harry has 1kg box of chocolates he eats 400g and his girlfriend eats165g how much chocolate is left in the box?
1Kg is the equivalent to 1000g so if Harry eats 400g there will be 600g left and if his girlfriend then eats 165g there will only be 435g left!
How many kilogram are in 43500mg?
1 kg is 1000g 1g is 1000mg This means that 43500mg = 43.5g (Divide by 1000) So: 435g=0.0435kg (Divide by 1000) To get straight there: We know that 1kg=1000000mg So, divide 43500 by 1000000. 43500mg=0.0435kg
