Question

You need 100.00 mL of H20 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/cm", the density of liquid plant food is 1.21

g/cm' and 1 cm° = 1 mL. How much of the

liquid plant food would you use?

Answer 1

6.05 g

Step-by-step explanation:

Use the density to convert the volume to a weight.

(5.00 mL) × (1.21 g/mL) = 6.05 g liquid plant food

You will need 6.05 g liquid plant food.
