1.

2. The equation to calculate Density is Mass / Volume. You are given that the density is 5.45 and the mass is 65; 5.45 = 65 / v. So v = 65 / 5.45; v = 11.93 mL (or if you want your answer to consider significant figures, v = 12 mL).

3.

m = 43.5 g

V = 50 mL

d = 43.5 g / 50 mL = 0.87 g/mL

Density of this cooking oil is 0.87 g/mL.
