Question

Density of a substance is 4g/m3 What would be
its mass if volume is 0.3cm3​

Answer 1

Answer:

m = 2.00 gm Δm = 0.01 gm

V = 5.0 cm³ ΔV = 0.1 cm³

d = m/V = 2/5 = 0.40 gm/cm³

density = d = m/V

=> Δd / d = Δm / m + ΔV/ V

= 0.01/2 + 0.1/5

= 0.025

Δd = 0.025 * 0.4 = 0.01 gm/cm³

d = 0.40 +- 0.01 gm/cm³
