Explanation:
The density of an irregular object can be determined using a graduated cylinder, water and a balance as follows.
The irregularly shaped object is weighed in a balance and its mass is recorded. The graduated cylinder is then filled with a given volume of water. This volume of water is also recorded. The irregularly shaped object is then introduced into the graduated cylinder containing the water and the change in volume of the water is recorded.
Volume of the object= change in volume of the water
Density= mass/volume
b)
If the beads weigh 50.217 g
Volume of beads = change in volume of water= 40.7 ml - 35.0ml = 5.7 ml
Density= mass/volume = 50.217 g/5.7 ml = 8.81 g/ml
Accepted value of the density of copper in g/ml = 8.94 g/ml
% error in density = |8.81-8.94|/8.94 ×100
% error in density = 1.45%
