How many grams of pumpkin are in 300 mL of a 30% pumpkin juice solution?

Question

How many grams of pumpkin are in 300 mL of a 30% pumpkin juice solution?

Answer 1

Well of the 300 ml, 30% will be pumpkin (0.30 x 300 = 90 ml) and 210 ml solute

90 ml = 90 cm³

So grams of pumpkin = 90 x density of pumpkin (in g /cm³)

This isn't given so you will have to Google that.
