You weigh three samples of the same metal, and find their masses to be 35.71 g, 39.04 g, and 40.81 g. the corresponding volumes are 3.9 ml, 4.5 ml, and 4.5 ml. what is the density, d, of the metal?

The density of metal is 8.97 g/mL

Explanation:

Density of a substance is defined as the ratio of its mass and volume. The chemical equation representing density of a substance is:  

        .......(1)

Mass of sample 1 = 35.71 g

Volume of sample 1 = 3.9 mL

Putting values in equation 1, we get:

Density of sample 1 = 9.16 g/mL

Mass of sample 2 = 39.04 g

Volume of sample 2 = 4.5 mL

Putting values in equation 1, we get:

Density of sample 2 = 8.68 g/mL

Mass of sample 3 = 40.81 g

Volume of sample 3 = 4.5 mL

Putting values in equation 1, we get:

Density of sample 3 = 9.07 g/mL

Putting values in above equation, we get:

Hence, the density of metal is 8.97 g/mL

the answer is a for sure mark brainliest i had got this right on usatestprep
