Answer

d = 2.65 $\frac{g}{mL}$

Work Step by Step

To find the density of quartz, apply the formula: d = $\frac{m}{V}$ We know the m of quartz piece 38.4 g. To find the volume we subtract the volume of water from the volume of water and quartz after the quartz was submerged into water. $V_{quartz}$ = 65.7 mL - 51.2 mL $V_{quartz}$ = 14.5 mL 2- Now we replace the volume of quartz into density formula: d = $\frac{m}{V}$ d = $\frac{38.4 g}{14.5 mL}$ d = 2.65 $\frac{g}{mL}$
