As far as I know, may be wrong :When pressure is multiplied by a number, the gas volume also gets multiplied by the same number. So, the answer can be found by doing: (3.4/1.97)(12), and the answer is about 20.71.
Answer:
F' = 3 N
Explanation:
Given that,
Two objects of equal mass have a force of gravity of 6 N between them.
If the mass of one is cut in half and the other stays the same such that,
m₁' = m₁ and m₂' = (m₂/2)
We need to find the new force. The gravitational force between two objects is given by :

We have, F = 6 N
New force,

So, the new force becomes 3 N.
This one is easy. It's just addition and subtraction. Add the partial pressure of Argon and the partial pressure of Helium:
152 kPa
<u>+305 kPa</u><u>
</u> 457 kPa
Next, subtract the result from the total pressure:
1015 kPa
<u>- 457 kPa</u>
558 kPa
