5.00 L of a gas is collected at 22.0 'C and 745.0 mmHg . When the temperature increases to 35'C what is the new pressure

The new pressure is 777.926 mmHg.

Explanation:

We use the ideal gas equation

.

where and are the pressure, volumes, moles, and temperature of the gas respectively. is the gas constant .

Initially, for the gas

therefore, the number of moles is

Now, when the temperature rises to 35°C, (assuming constant volume) we have

or in mmHg this is

find the surface area of the sphere to the nearest square unit. use a calculator.

a. 254 in.2

b. 64 in.2

c. 127 in.2

d. 1,018 in.2
