Acontainer has the dimensions of 10 cm x 50 mm x 0.2 m. it is filled completely with 5.0 kg of a powdery ore. what is the density of the ore in g/cm3 ? (d=m/v)
0.05 g/cm3
5.0 g/cm3
50 g/cm3
500 g/cm3

B

Explanation:

5 kg = 5 kg * 1000 grams / kg = 5000 grams

10 cm does not require any conversion.

50 mm = 50 mm * 1 cm/10 mm = 5 cm

0.2 m = 0.2 m * 100 cm / 1 m = 20 cm

V = 10 cm * 5 cm * 20 cm

V = 1000 cm^3

Density = 5000 grams / 1000 cm^3 = 5 grams / cm^3
