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.​

Respuesta :

TheSection

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

  1. The mass of 20mL of olive oil is 18.4g
  2. The volume of 20g of olive oil is 21.74mL

CALCULATION OF DENSITY:

  • The density of a substance can be calculated by dividing the mass by its volume. That is;

Density = mass (g) ÷ volume (mL)

The density of olive oil is given as: 0.92g/mL

QUESTION 1:

  • Hence, the mass of 20mL (volume) olive oil is calculated as follows:

Mass = density × volume

Mass = 0.92g/mL × 20

Mass of olive oil = 18.4grams.

QUESTION 2:

  • The volume of 20g (mass) of olive oil is calculated as follows:

Volume = mass ÷ density

Volume = 20 ÷ 0.92

Volume of olive oil = 21.74mL

Therefore;

  1. The mass of 20mL of olive oil is 18.4g
  2. The volume of 20g of olive oil is 21.74mL
