Answer 1

Answer:

so much to me about it but it was good

Answer 2

Answer:

Answer. 7. ans:- 2.66 x 22.4 = 59.58 =

liters.

Answer.8. ans..

п

At STP, the temperature is 273K and the pressure is 1 atm. The proportionality constant,

R, is equal to 0.0821

Lx atm

mol x K

Now we have to rearrange the equation to solve

for n:

n =

PV

RT

Plug in the given values:

n

=

1 atm x 135 L

0.0821

Latar

mol x K

n = 6.02mol
