Expert Solution

Consider the given data: Cost of 76 pound of mercury = $134.50 Density of mercury=13.534 g/cm Calculate the cost of one pound of mercury as shown below: Cost of 76 pound of mercury = $134.50 $134.50 Cost of Ipound of mercury = 76 pounds = $1.77 xl pound Hence the cost of one pound of mercury is $1.77 (2) Use the following relation to calculate the price of one gram of mercury: 1 pound = 453.6g Cost of 453.6g of mercury = Cost of 1 pound of mercury = $1.77 $1.77 X1.08 Cost of 1.0 g of mercury =- 453.6g = $0.0039 Hence the cost of 1 g of mercury is $0.0039 Use the following relation to calculate the price of one cm of mercury: Density of mercury = 13.543 g/cm Cost of 1cm' of mercury = Cost of 1g of mercury x 13.543 =$0.0039x13.543 = $0.0528 Thus the price of 1cm' mercury is $0.0528.

Use the following relation to calculate the price of one cubic inch of mercury: 1cm=0.061 cubic inch Cost of 0.061 cubic inch of mercury = Cost of 1 cm of mercury = $0.0528 $0.0528 Cost of 1cubicinch of mercury = – x1.0 cubic inch 0.061 cubic inch = $0.866 Hence the cost of one cubic inch of mercury is $0.866. 1. Calculate the cost of 4.400 cubic inches as shown below: Cost of 1 cubic inch of mercury=$0.866 Cost of 4.400 cubic inch of mercuy=$0.866 x 4.400 = $3.81 4.400 cubic inches of mercury is required to make one manometer therefore, the cost 1 manometer is, Cost of 1 manometer = Cost of 4.40 cubic inches of mercury = $3.81 Thus, the cost of 1 manometer is $3.81). 2. Now, calculate the cost of 13 manometers as shown below: Cost of 13manometers = Cost of imanometer x 13 = $3.81x13 = $ 49.53 Thus, the cost of 13 manometers is $49.53).
