The mass of the block in kg is 6.65 kg for a rectangular block of tungsten has a length of 7.90 cm, a width of 2.30 cm, and a height of 1.90 cm as the density of tungsten is 19.28.
Density is the mass of a substance present per unit volume and it is the ratio of mass and the volume of the substance given by gram per centimeter cube.
The mass of tungsten is density multiplied by volume,
volume = 7.90 cm × 2.30 cm × 1.90 cm
19.28 × 53.53 = 6.65 kg.
Therefore, the density of tungsten is 19.28, and the mass of the block in kg is 6.65 kg for a rectangular block of tungsten has a length of 7.90 cm, a width of 2.30 cm, and a height of 1.90 cm.
