Answer:
Density of iron shot is 7.92 g/mL.
Explanation:
Given data:
Mass of water + iron + graduated cylinder = 94.74 g
Mass of water + graduated cylinder = 66.24 g
Volume of water = 45.50 mL
Volume of water + iron shot = 49.10 mL
Density of iron = ?
Solution:
First of all we will calculate the volume of iron shot.
Volume of iron shot= (Volume of water + iron shot) - Volume of water
Volume of iron shot= 49.10 mL - 45.50 mL
Volume of iron shot= 3.6 mL
Now we will calculate the mass of iron shot.
Mass of iron shot = (Mass of water + iron + graduated cylinder ) - Mass of water + graduated cylinder
Mass of iron shot = 94.74 g - 66.24 g
Mass of iron shot = 28.5 g
Now we will calculate the density of iron shot.
d = m/v
d = 28.5 g / 3.6 mL
d = 7.92 g/mL
Density of iron shot is 7.92 g/mL.
