Question

A. A copper lump displaces 100 mL of wall
in a measuring cylinder. If the density of
copper is 8400 kg m-3, find the mass of
8. TI
the lump.​

Answer 1

$\begin{gathered}{\Huge{\textsf{\textbf{\underline{\underline{\purple{Answer:}}}}}}}\end{gathered}$

100ml = 0.0001m³

As we know,

ρ = m/v

Where,ρ = density.

∴m = ρ × V

∴m = 8400 × 0.0001

∴m = 0.84kg
