1
Q

What are the different measurements of gases (related to 1atm)

A

1atm = 760mmHg = 760torr = 101.325 kPa

2
Q

What is temperature at STP? What is it at standard state?

A

STP: 0º (273K)

Standard state: 25º (298K)

3
Q

At stp how much volume does one mole of gas occupy?

A

22.4L

4
Q

How do you get a density out of a PV=nRT ?

A

p= m/V2

V2 = V1 (P1/P2)I(T2/P1)

5
Q

What is Avogadros principle?

A

All gases at constant temp and pressure occupy volumes that are directly proportional to the number of moles of gas present

**one mole of any gas will occupy 22.4 L at STP

n/V = k. K= constant

n1/V1 = n2/V2

Use when T and P are constant

6
Q

Boyle’s law

A

P1v1=p2v2

7
Q

Charles law

A

At constant p, V1/t1=V2/t2

8
Q

Dalton’s law

A

Combined gas law

Ptotal= p1 + p2 +…

(Total of partial pressures)

9
Q

How is a partial pressure measured?

A

Pa= XaPtotal

Xa = moles of gas A / total moles of gas

10
Q

Henrys law

A

[A] = Kh x PA.

[A]1 / P1 = A2/P2 = Kh
