Question

please answer by solving question number 15 (b) part

Answer 1

mass = 18 g & volume = 10 cm3
if assumed give density = 1.8 g cm3

thus mass = 18g = 18 / 1000 = 0.018 kg
& volume = 10 cm 3 = 10 / 100 *100 * 100= 0.00001 m3
density = 0.018 / 0.00001 = 1800 kg m3-

Answer 2

density=18\1000=0.018 kg
volume=10cube
100000=0.00001
0.018\0.00001 =1800kg\mcube
