Question

5.74 g of a substance occupies a volume of 1.2 cm3. Calculate its density in significant figures.

Answer 1

Density= Mass/ Volume
5.74/1.2= 4.78
in significant figures = 4.7

Answer 2

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

• 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${cm}^-3$.
