Question

who will answer Me I will follow him and make him brainlist​

Answer 1

Explanation:

example 1 ) PV = nRT:

(660.0 mmHg / 760.0 mmHg/1.00 atm) (11.0 L) = (n) (0.08206 L atm / mol K) (298 K)

conversion from mmHg to atm and from Celsius to Kelvin

example 5

16.89 atm.

Explanation:

Step 1:

Data obtained from the question

Number of mole (n) = 2.3 mol

Temperature (T) = 40°C = 40°C + 273 = 313K

Volume (V) = 3.5L

Pressure (P) =..?

Gas constant (R) =0.0821 atm.L/Kmol

The pressure exerted by the gas can be obtained by using the ideal gas equation as shown below:

PV = nRT

Divide both side by V

P = nRT /V

P = 2.3 x 0.0821 x 313 / 3.5

P = 16.89 atm.

Therefore, the pressure exerted by the gas is 16.89 example 2=

0.238 moles
