f the density of a substance is 2 × 103 kg m–3, thenthe mass of 5 m3 of this substance is ______.(a) 1000 kg (b) 10000 g(c) 10000 kg (d) Both (a) and (b)
Question
If the density of a substance is 2 × 10<sup>3</sup> kg m<sup>–3</sup>, then the mass of 5 m<sup>3</sup> of this substance is ______.
(a) 1000 kg
(b) 10000 g
(c) 10000 kg
(d) Both (a) and (b)
Solution
To find the mass of a substance, we can use the formula:
Mass = Density × Volume
Given that the density of the substance is 2 × 10^3 kg/m^3 and the volume is 5 m^3, we can substitute these values into the formula:
Mass = (2 × 10^3 kg/m^3) × (5 m^3)
Simplifying the expression, we get:
Mass = 10^4 kg
Therefore, the mass of 5 m^3 of this substance is 10,000 kg.
So, the correct answer is (c) 10,000 kg.
