Mass of a sample = M = ?
Density of a sample = D = 8.9 g/cm³
Volume of the sample = 6 cm³
By using the formula = D = M / V
Density = Mass / Volume
Mass = Density x Volume
M = D x V
Putting the values of density and mass of the sample
M =8.9g/cm³ x 6cm³ =53.4 g
So, the mass of the material in grams is 53.4g
