diket:
h₁ = 6 cm
ρ₁ = 1,8 g/cm³
h₂ = 10 cm
h₃ = 8 cm
h₂₃ = 12 cm
ditanya:
massa jenis zat 3 (ρ₃)....?
jawab:
- menentukan ρ₂ lebih dulu
6 cm x 1,8 g/cm³ = 10 cm x ρ₂
ρ₂ = (6 cm x 1,8 g/cm³) / 10 cm
ρ₂ = 1,08 g/cm³
- menentukan ρ₃
8 cm x ρ₃ = 12 cm x 1,08 g/cm³
ρ₃ = (12 cm x 1,08 g/cm³) / 8 cm
ρ₃ = 1,62 g/cm³
Jadi, besar massa jenis zat cair ketiga adalah 1,62 g/cm³. (C)
