If A bottle contains 500 mL of ketchup and has a density of 1.43 g What is the mass of the bottle in grams?

Answer 1

Question as asked cannot be answered. We know that the bottle can contain 500 mL of ketchup, but we don't know the volume of the material from which the bottle is made, nor the correct density (the figure given as density, 1.43 g, is actually a mass). In addition even if we assume that the figure given for density is 1.43 g/mL is an actual density, from the sentence structure we have a volume for ketchup, and a density of the material in the bottle ("density" refers back to bottle, not to ketchup—"Bottle contains ... and has a density of"). If the one who posed the question meant to write, "If a bottle contains 500 ml of ketchup, and the ketchup has a density of 1.43 g/l, what is the mass of the ketchup in the bottle in grams", then the original answer to the question 715g/mL mass = density x volume is correct.
