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?

Show your work.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.Related Questions
