A bottle can hold up to 1kg of water. How much edible vegetable oil can you hold in this bottle? (ρ water = 1.0 × 103 & nbsp; kg / m3, ρ oil = 0.9 × 103 & nbsp; kg / m3)

A bottle can hold up to 1kg of water. How much edible vegetable oil can you hold in this bottle? (ρ water = 1.0 × 103 & nbsp; kg / m3, ρ oil = 0.9 × 103 & nbsp; kg / m3)

(1) ∵ ρ = MV, ∵ bottle volume: v = V water = m water ρ water = ikg 1 × 103kg / m3 = 1 × 10-3m3; (2) ∵ ρ = MV, the maximum mass of edible vegetable oil in the bottle: m oil = ρ oil, v = 0.9 × 103kg / m3 × 1 × 10-3m3 = 0.9kg

A bottle can hold 1kg water. Which of the following liquids can the bottle hold 1kg? (ρ mercury ＞ ρ water ＞ ρ vegetable oil ＞ ρ alcohol ＞ ρ gasoline) ()
A. Alcohol B. gasoline C. vegetable oil D. mercury

Different substances with the same mass have the same density and larger volume. Therefore, the bottle that can hold 1kg water can not hold 1kg substance with lower density. Because of ρ mercury ＞ ρ water ＞ ρ vegetable oil ＞ ρ alcohol ＞ ρ gasoline, the bottle that can hold 1kg water can not hold 1kg substance with lower density than water

One bottle can hold 1kg of water. How many kilos of edible oil can be contained in several bottles

In this problem, the volume of bottle is fixed, the volume of water and oil is equal, V water = 1 cubic decimeter, m oil = ρ oil * V = ρ oil * 1 cubic decimeter
