Question

Exercise 6: The density of a substance is defined by the equation d nm =- Where d stands for density, m stands for mass and v stands for volume So if a sample "A" has 3.45 g of mass and 3.25 ml, we can obtain the density by dividing 3.45 g by 3.25 ml. a) Obtain the density of sample "A" using the above values for mass and volume. The units should be "g/ml" b) Another sample "B" has 4.56 ml and 5.49 g. What is its density? Show your calculation c) Which sample, "A" or "B", has the highest density? MOss .

Explanation / Answer

Density (d) = Mass (m)/Volume (v) (Given)

d = m/v

Mass of sample A = 3.45g (given)

Volume of sample A = 3.25ml

(a) Density of sample A = 3.45/3.25

= 1.061g/ml

(b) Mass of sample B = 5.49g

Volume of sample B = 4.56ml

Density of sample B = 5.49/4.56

= 1.204g/ml

(c) Density of sample A = 1.061g/ml

Density of sample B = 1.204g/ml

Clearly density of sample A is greater than density of sample B.
