Answer:
Explanation:
a) Find the price of one cubic inch of mercury by calculating intermediate values.
• What is the price of one pound of mercury?
• What is the price of one gram of mercury?
•What is the price of one cubic centimeter of mercury?
• What is the price of one cubic inch of mercury?
b) It takes 3.700 cubic inches of mercury to make one manometer. Find the price of the mercury used to make 19 manometers by first calculating the cost of mercury for one manometer.
• price of one pound of Mercury = cost of flask of mercury / pounds in the flask
= $130 / 76 pounds
= $1.71
price of one pound of Mercury = $1.71
• Price of one gram of mercury
1 pound = 453.6 grams
76 pound = 34473 grams
Price of one gram of mercury = price of mercury per pound / grams in one pound
= $1.71/ 453.6 grams
= $0.00377
Price of one gram of mercury = $0.00377
• Price of one cubic centimeter of mercury
Grams per cubic centimeter = 13.534 g/cm^3
price of one cubic centimeter =
Grams per cubic centimeter × price per grams
= 13.534 g/cm^3 x $0.00377
=$0.051
• Price of one cubic inch
1 cubic inch = 16.387 cubic centimeter
price of one cubic inches= 16.387 cubic centimeter × price per cubic centimeter
= 16.387 cubic centimeter x $0.051
=$ 0.836
(b) price of 3.700 cubic inches = price per cubic inches × 3.700 cubic inches
= $0.836 x 3.7
=$ 3.094
3.700 cubic inches = 1 manometer
price of one manometer = $3.094
Price of 19 manometers = $3.094 x 19
= $ 58.794
