Question
A piece of metal with a mass of 10.5 g was placed into a graduated cylinder which contained water. Upon complete submersion the water level in the graduated cylinder rose 1.47 mL . What is the likely identity of the metal? A Ag,d=10.5g/cm^3 B Pa,d=15.4g/cm^3 C Zn,d=7.14g/cm^3 D Ca,d=1.54g/cm^3

### C.
Explanation
## Step 1: Calculate the density of the metal### Density is given by the formula
, where
is the mass and
is the volume. Here,
g and
mL (which is equivalent to 1.47 cm³ since 1 mL = 1 cm³). Thus,
.## Step 2: Perform the division###
.## Step 3: Compare the calculated density with the given options### The calculated density (7.14 g/cm³) matches the density of zinc (Zn) from the given options.
