One day, Xiaoming went to the kitchen to cook. At first, he put water first, then oil. He found oil floating on the water, so he guessed that the density of Jinlong fish oil was smaller.
The total mass of beaker and oil is100g+50g+10g+2.4g =162.4g; Mass of oil in the measuring cylinder =162.4g-108.4g = 54g; The volume of oil in the measuring cylinder is 60 ml; ; The density of oil ρ = MV = 54g60cm3 = 0.9g/cm3.
See the following table for specific data:
Total mass of beaker and oil (g) mass of beaker and residual oil (g) mass of oil in measuring cylinder (g) volume of oil in measuring cylinder (ml) density of Jinlong fish oil (g/cm3)162.4108.4 54 600.9.
