Answer 1

density=mass/volume
=5.74/1.2
=4.78g/cm^3

Answer 2

${\huge{\underline{\underline{\mathfrak{\blue{♡ANSWER♡}}}}}}$

• There are 3 significant figures in the measured mass wherr there are only 2 significant figures in the measures volume .
• Hence the density should be expressed to only 2 significant figures.

Density = $\frac{5.74}{1.2}$ g ${cm}^-3.</p><p></p><p></p><p></p><p></p><p>={4.8}$ g${cm}^-3$.
