The density of 400cm³ of palm oil was 0.9 g/cm³ before frying. If the density of the oil was 0.6 g/cm³ after frying, assuming no loss of oil due to spilling, its new volume was A. 360cm³ B. 600cm³ C. 240cm³ D. 800cm³ E. 450cm³
ANSWER: Option B
Density = mass/volume and the question pointed out that assuming no loss of oil due to spilling, it means that the mass is conserved.
So we have density × volume = constant
From there, we can have
D1 × V1 = D2 × V2
Substitute the values inside that formula to arrive at your answer!
