The density 400cm3 of palm oil was 0.9gcm-3 before frying. If the density of the oil was 0.6gm-3 after frying,assuming no loss of oil due to spilling, its new volume was
  • A.
    360cm3
  • B.
    600cm3
  • C.
    240cm3
  • D.
    800cm3
  • E.
    450cm3
Correct Answer: Option B
Explanation

Since no loss of oil,
Density x volume = constant
D1V1 = D2 x V2
0.9 x 400 = V2
V2 = 600cm3
