The answer is 15.
Step-by-step explanation: To find the answer you have to think of a number line and think how many spaces do I have to jump to get to seven from negative eight.So you have to add eight just to get to 0. Now add 7 to get to 7. Together it equals 15.
This question requires the manipulation of the Ideal Gas formula. By moving the variables around, you'll get :
V = nRT/P
n = PV/RT
Multiply each of the numbers by a ten to a power that they both become whole numbers.
0.67 *

= 67
0.3 *

= 30
Divide as usual.
67 / 30 = 2

So, the answer is 2 1/3.
