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
