Question

If a large marshmallow has a volume of 3.00in3 and density of 0.242 g/cm3, how much would it weigh in grams? 1 in3=16.39 c

Answer 1

A volume:
V = 3.00  in³
1 in³ = 16.39 cm³
V = 3.00  ·  16.39 = 49.17 cm³
0.242 g/cm³  ·  49.17 g =  11.899 g²  ≈ 11.90  g
Answer:  It would weigh 11.90 grams.
