Jason measures three values of density for his unknown. The values he obtains are: 1.019 g/mL 1.498 g/mL 1.572 g/mL What is the
jok3333 [9.3K]

<u>Answer:</u> The average of the densities of the given measurements is 1.363 g/mL

<u>Explanation:</u>

The equation used to calculate density of a substance is given by:

\text{Density of a substance}=\frac{\text{Mass of a substance}}{\text{Volume of a substance}}

We are given:

First measured value of density, d_1 = 1.019 g/mL

Second measured value of density, d_2 = 1.498 g/mL

Third measured value of density, d_3 = 1.572 g/mL

Putting values in above equation, we get:

\rho_{mix}=\frac{d_1+d_2+d_3}{3}

\rho=\frac{1.019+1.498+1.572}{3}\\\\\rho=1.363g/mL

Hence, the average of the densities of the given measurements is 1.363 g/mL

A substance has a volume of 10.0 cm³ and a mass of 89 grams. What is its density?
lara [203]

Answer:

8.9 g / cm^3

Explanation:

Density = mass / volume

We are given volume which is 10.0cm^3 (cm^3 is just fancy way of saying ml), and mass of 89 gram. Just plug them in respective spots.

Density = 89 / 10.0 = 8.9 g / cm^3
