Question

A 76.00-pound flask of mercury costs $139.00. The density of mercury is 13.534 g/cm3.

a) Find the price of one cubic inch of mercury by calculating the following intermediate values.

What is the price of one gram of mercury?

What is the price of one cubic centimeter of mercury?

It takes 3.300 cubic inches of mercury to make one manometer.

Find the price of the mercury used to make 13 manometers by first calculating the cost of mercury for one manometer.

What is the price of mercury used to make one manometer?

What is the price of mercury used to make 13 manometers?

76 ppound has cost= 139 dollars

1 pound has cost = 139/76 dollars

or 435.6 gram has cost =139/76 = 1.83 dollars

1 gram has cost = 0.00412 dollars

Now volume of flask = 76*435.6/13.534 = 2446.10 cm^3 = 149.212 cubic inch

So 149.212 cubic inch has cost = 139 dollar

1 cubic inch has cost = 139/149.212 = 0.93156 dollars.

NOw

1 cubic inch mercury = 0.93156 dollar

So 3.3 cubic inch mercury or 1 manometer = 3.08748 dollar

NOw to make 13 manometer = 13 * 3.0748 = 40.13724 dollar
