Question

Iron has a density of 7.9 space straight g divided by cm cubed. How much mass is in a 10 space cm cubed sample of iron? Question 10 options: 17.9 g 79 g 1.26 g 0.79 g

Answer 1

Answer:

79 g

Explanation:

Density (d) of iron = 7.9 g/cm³

Volume of the iron (V) = 10 cm³

Mass of the iron (m) = ?

Solution:

Formula will be used

                            d = m/V

As we have to find mass so rearrange the above equation

                              m = dV . . . . . . . . . . . (1)

Put values in above equation 1

                         m = 7.9 g/cm³ x 10cm³

                         m = 79 g

So,

mass of iron = 79 g
