What is the density of a 9.343 gram piece of metal that causes the level of water in a graduated cylinder to rise from 50.0 mL to 53.5 mL?
A
1.87 g/mL
B
3.12 g/mL
C
2.67 g/mL
D
2.34 g/mL
Verified step by step guidance1
Identify the formula for density, which is \( \text{Density} = \frac{\text{Mass}}{\text{Volume}} \).
Determine the mass of the metal, which is given as 9.343 grams.
Calculate the volume of the metal by finding the difference in water levels in the graduated cylinder: \( 53.5 \text{ mL} - 50.0 \text{ mL} = 3.5 \text{ mL} \).
Substitute the mass and volume into the density formula: \( \text{Density} = \frac{9.343 \text{ g}}{3.5 \text{ mL}} \).
Perform the division to find the density of the metal in grams per milliliter (g/mL).
