If the mass of a material is 44 grams and the volume of the material is 6 cm^3, what would the density of the material be?

Svetlanka [38]

Density is mass per unit volume.

For the given material that has a mass of 44 grams occupying a volume of 6 cm^3, we divide the mass by the volume, i.e.

density of material = 44 grams / 6 cm^3 = 44/6 grams/cm^3 = 7.3 g/cm^3 (to two significant figures)

Rudik [331]

Answer:

Step-by-step explanation

Car A started 10 miles east of Johnstown based on the fact he traveled 90 miles in 2 hours but was 100 away from Johnstown

Car B started 20 miles away, so that mean Car B was 10 more miles east than Car A when they started.
