Gianna · Answer 1

The density of the substance is obtained by dividing its mass by its volume. Density is an intensive property which means that its value does not depend on the amount of substance and will always stay the same for same conditions.

d = 84.7 g / 46.7 cm³ = 7.75 g / x cm³

The value of x is approximately 4.27 cm³.
