Question

a density bottle has a mass of 0.04kg when empty a mass of 0.20kg when some quality of steel ball bearing is added to it and a mass of 0.24kg when the remainder of the bottle is filled with water. if the density bottle weight 0.1kg when filled with water. calculate the relative density of the steel ball bearing.​

Answer 1

Bottle = .04

Bottle + Bearing = .20

Bottle + Bearing + Water = .24

Bottle + Water = .1

Full bottle of water weighs = .06

Weight of bearing = .16

What volume of water does the bearing replace????

It takes .14 of bottle to replace bearing leaving .06 of water

Density = 16 / 6 = 2.67

Check: probably should use volumes
