Question

Volume segelas air 8 x 10^-6 m3. Hitunglah massa jenis air di gelas jika massa jenis air 1,0 x 10^3 kg/m3 !
(Rumus : m=rho.v dengan m = massa, rho = massa jenis, v = volume) !

Answer 1

M = 1,0 x 10^3 x 8 x 10^-6
= 8 x 10^-3 kg

Answer 2

Karena berlakunya rumus:
p = m/v

Maka,
m = p v
m = (1,0 x 10³ kg/m³) x (8 x 10⁻⁶ m³)
m = 8 x 10³⁻⁶ kg
m = 8 x 10⁻³ kg
Atau:
m = 8 gram
