A 70 cm3 silver ingot has a mass of 735 g 1) What is the mass of a 25 cm3 silver ingot?

A 70 cm3 silver ingot has a mass of 735 g 1) What is the mass of a 25 cm3 silver ingot? 2) what is the volume of a 450 g silver bar?

1) Find out what is the mass of a 25 cm3 silver ingot if the 70 cm3 ingot has a mass of 735 g:

70 cm3 – 735 g

25 cm3 – x g

x = 25 * 735: 70;

x = 18375: 70;

x = 262.5 (g) is the mass of a 25 cm3 silver ingot.

2) Let us determine what is the volume of a silver ingot weighing 450 g, if an ingot with a volume of 70 cm3 has a mass of 735 g:

70 cm3 – 735 g

x cm3 – 420 g

x = 70 * 420: 735;

x = 29400: 735;

x = 40 (cm3) – the volume of a silver ingot weighing 450 g.

Answer: The mass of a 25 cm3 silver ingot is 262.5 g; the volume of a silver ingot weighing 450 g is 40 cm3.
