We’re being asked to determine if the sphere will float or sink in chloroform given that the density of chloroform 1.48 g/mL, and the mass of the sphere is 311 g and a diameter of 7.61 cm.
Recall that density is the ratio of the mass and volume of an object:
Also, the volume of a sphere is given by:
where r = radius. Recall that diameter = 2r.
Lignum vitae is a hard, durable, and extremely dense wood used to make ship bearings. A sphere of this wood with a diameter of 7.61 cm has a mass of 311 g.
Will the sphere float or sink in chloroform? (The density of chloroform is 1.48 g/mL).
