Question

Q15): A piece of zinc of mass 115 g has a volume of 10 cubic centimetre, Calculate the density of zinc ?* a)11500 g/cm
b)150 g/cm3
c) 11.5 g cm
d) 1.15 g/cm
PLS ANSWER THIS FAST ​

Answer 1

$\large \rm \red {\underbrace{\underline{Elucidation:-}}}$

$\sf \blue {\underline{\underline{Provided\: that:}}}$

$\mapsto \tt {Mass\: of\: zinc\: piece (m)=115g}$

$\mapsto \tt {Volume\: of\: zinc\: piece(v)=10cm^{3}}$

$\sf \pink {\underline{\underline{To\: determine:}}}$

$\mapsto \tt {Density\: of\: zinc\: piece(ρ)=?}$

$\sf \purple {\underline{\underline{We\: know:}}}$

$\implies \tt {\boxed{\underline{ρ=\frac{m}{v}}}}$

➻where,

★ρ denotes density

★m is the mass

★v is the volume.

➻supplanting the given values,

$\large \colon \to \tt {ρ=\frac{115g}{10cm^{3}}}$

$\colon \implies \tt \green {\boxed{\underline{Density(ρ)=11.5g/cm^{3}}}}$

$\sf \orange {\underline{\underline{Therefore,}}}$

➻Density of zinc is $\tt{11.5g/cm^{3}}$ respectively.

★"Option-C" is the correct answer.
