density in kg/L.



i need help ASAP

Answer 1

Explanation:

w = 5 cm

h = 6 cm

L = 7 cm

V = 5 * 6 7

V = 210 cm^3

1 L = 1000 cm^3

x L = 210 cm^3

1000 cm^3 *x = 210 cm^3

x = 0.210 L

11.392 grams = 11.392 kg/ 1000

mass = 0.011392 kg

density = mass / volume

density = 0.011392 / 0.210

density = 0.0367 kg/L to 3 places of accuracy.
