If the density is .760g/mL how may grams are contained in a 24 cubiccentimetress?

Question

I dont know even how to start anyone know what to do?

Answer 1

1 ml of water at sea level and 25 degrees Celsius (I think) is equal to 1 cubiccentimetre. So 24 cubiccentimetres with a density of 0.760g/ml is equal to 24 x 0.760 = 18.24g.

Note that the density of a substance changes as you change temperature due to thermal expansion. I think all given densities of a substance are supposed to be taken at 25 degrees, but I could be wrong.

Answer 2

mL &cubiccentimetres are inter-changable

? g = 24 cm3 @ 0.760 g / cm3 = 18.24 grams

your answer (2sigfigs): 18 grams
