Question

6) Given that the density of olive oil is 0.92 g/mL, calculate the followin a. The mass of 20.0 mL of olive oil. The volume of 20.0 g of olive oil.​

Answer 1

We are given:

Density of Olive oil = 0.92 g / mL

Mass of 20 mL Olive oil:

We know that the density = 0.92 grams / mL

multiplying the numerator and the denominator by 20

Density = 0.92 * 20 grams / 20 mL

Density = 18.4 grams / 20 mL

So, we have 18.5 grams in 20 mL of Olive oil

Volume of 20 grams Olive oil:

We need to multiply the numerator and the denominator of density by a number, that when multiplied by 0.92 will give 20

let that number be x:

0.92 * x = 20

x = 20/0.92

x = 21.74 (approx)

Multiplying the numerator and the denominator by x:

Density = 0.92 grams / 1 mL

Density = 0.092 * 21.74 / 21.74 mL

Density = 20 grams / 21.74 mL

So, we can see that 20 grams of the oil will have the volume 21.74 mL
