A piece of metal with a mass of 131 g is placed in a 50 mL graduated cylinder. The water level rises from 20. mL to 35 mL. What is the density of the metal?
density=mass/volume=131g/15ml
density = mass/volume
mass = 13.1 g
volume you get from the water displaced; i.e., 35 mL-20 ml = ?
That mass is 131 g. Bob P is right.
To find the density of the metal, we need to use the formula:
Density = Mass / Volume
Step 1: Find the volume of the metal
The volume of the metal can be found by subtracting the initial water level (20 mL) from the final water level (35 mL):
Volume = Final water level - Initial water level
Volume = 35 mL - 20 mL = 15 mL
Step 2: Convert the volume to cubic centimeters (cm³)
Since density is typically measured in g/cm³, we need to convert mL to cm³. Since 1 mL is equal to 1 cm³, the volume remains the same:
Volume (in cm³) = 15 cm³
Step 3: Convert the mass to grams (g)
The mass is given as 131 g, so no conversion is required.
Mass = 131 g
Step 4: Calculate the density
Now that we have the mass and volume in the appropriate units, we can use the formula to calculate the density:
Density = Mass / Volume
Density = 131 g / 15 cm³
Finally, we can divide the mass by the volume to find the density:
Density = 8.73 g/cm³
Therefore, the density of the metal is 8.73 g/cm³.
