Explanation / Answer

1) 1.0 cm3 = 0.001 L

1.435 g = 0.001 L

1000 g (1.0 Kg) = 1000 x 0.001 / 1.435 = 0.70 L

0.70 L size bottle required.

2) 100 mL water can dissolve 71.0 g salt

55.0 mL water can dissolve 55.0 x 71.0 / 100 = 39.05 g salt

answer = 39.05 g

3) % m/v = (mass of solute / volume of solution) x 100

25.0 = (mass of solute / 525) x 100

mass of solute / 525 = 0.25

mass of solute = 131.25 g

mass of pure ingredient = 131.25 g
