Question

a) A gas has a volume of 7.0 liters and mass of 4.44 x105 micrograms. What is its density? b) A certain liquid has a density of 0.855 g/ml. How manyLITERS would weigh 1.00 kg? c) A solid block of substance is 74.0 cm by 55.0 cm by29.0 cm and it weighs 625 kg. Assuming that it did not chemicallyreact with water?

Explanation / Answer

We know that : density = weight of the substance / volume of thesolution              = 4.44 x 105 x 10-6 g / 7 x103 ml               = 6.34 x 10 -5 g / ml      volume of the solution = mass of the substance / density of the solution                                                = 103   g / 0.855 g / ml                                           = 1.2 x 10 3 ml       volume of the block of thesubstance = length x breadth x height                                                                = ( 74 x 55 x 29 ) cm3                                                                 = 118030 cm3         density of thesubstance = mass / volume                                              = 625 x 103 g / 118030 cm3                                               = 5.295 g / cc               It shows that the density of the substance is heavier than that ofthe water so they chemically cannot react with             each other.       volume of the block of thesubstance = length x breadth x height                                                                = ( 74 x 55 x 29 ) cm3                                                                 = 118030 cm3         density of thesubstance = mass / volume                                              = 625 x 103 g / 118030 cm3                                               = 5.295 g / cc               It shows that the density of the substance is heavier than that ofthe water so they chemically cannot react with             each other.                                               = 5.295 g / cc               It shows that the density of the substance is heavier than that ofthe water so they chemically cannot react with             each other.
