Question

An empty relative density bottle has a mass of 25g.When filled with a liquid of relative density 0.92g,its mass became 85g.Calculate the mass of the bottle when full of water.

Answer 1

85 g = mass bottle + liquid
-25 g = mass empty bottle
------------------------------
60 g = mass liquid of density 0.92 g/mL
volume of liquid = volume bottle = mass/density = 60/0.92 = 65.2 mL
65.2 mL H2O with density 1.00 g/mL has a mass of 65.2 g. Place that in the empty bottle weighing 25 g, the bottle will weigh 25 + 65.2 = ? grams
Watch significant figures.
