Required practical 5 - Density: Part 1 - Calculating the density of a regularly shaped object Flashcards
1
Q
Outline the basic steps of the practical
A
1) Measure the dimensions of the regular shape and calculate the volume.
2) Measure the mass of the shape using a calibrated balance.
3) Calculate density from the mass and volume.
2
Q
What equation is used to calculate density?
A
Density = mass / volume
3
Q
What unit is used for density?
A
kg/m³
4
Q
What piece of equipment is used to measure the object’s mass? What must you do before using it?
A
A digital balance, which should be zeroed before placing the object on it to avoid a zero error.
5
Q
How do you convert g/cm³ to kg/m³?
A
Multiply the value by 1000.
