If 3.25 g N2 gas is introduced into an evacuated 1.50 L flask at 325 K, what is the pressure inside the flask (in atm)?

2.06 atm

Explanation:

The computation of the pressure inside the flask is shown below;

As per the ideal gas law

we know that

P V = nRT

where

V = 1.50L

T = 325 K

R = 0.0821

Now moles of N_2 is

= 3.25 ÷ 28

= 0.116 mol

Now

P = NRT ÷ V

= 0.116 × 0.0821 × 325 ÷ 1.50

= 2.06 atm

the mantle

explanation:

earth is divided into three layers: the crust or the outermost layer on which we live; the underlying, middle layer - the mantle - and the core (the innermost layer of earth).

aquifers are bounded above and below by impermeable rock. the driving force of groundwater movement in confined aquifers is pressure, rather than gravity.
