Answer 1

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

• 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${cm}^-3$.

Answer 2

Answer:

Explanation:

Density=Mass/Volume=5.74/1.2=

4.8g/cm3.....
