Answer
Since density ($=8.92 g/mL$) has only 3 significant figures, the answer can only have 3 significant figures $V=5.97 cm^{3}$
And the first uncertain digit is $7$
Work Step by Step
The number of significant figures in the answer is set by the value with the least number of significant figures in question.
Since density ($=8.92 g/mL$) has only 3 significant figures, the answer can only have 3 significant figures $V=5.97 cm^{3}$
And the first uncertain digit is $7$
If the value of density is rounded from $8.924g/cm^{3}$ the value of volume will change to $\frac{53.275}{8.924}\approx5.9699cm^{3}$ the value of $7$ will change to $6$ . So, $7$ is the first uncertain digit.
