You need 100.00 mL of H2O and 5.00 mL of liquid plant food to make a solution for your plants. You forgot to bring a measuring cup out to the greenhouse, but you do have a scale and know that the density of H2O is 1.00 g/cm3, the density of liquid plant food is 1.21 g/cm3 and 1 cm3 = 1 mL. How much of the liquid plant food would you use?
