1 mole N2
I think it is correct
Answer:
you need only one independent variable because if not, you wont know what factors have changed your experiment.
Explanation:
Physical science , earth science,and life science are the branches of natural science
P1V1 = P2V2
P1 = 720 mmHg
V1 = 450. mL
P2 = 760 mmHg (this is the pressure at STP)
Use these to solve for V2:
(720)(450) = 760V2
V2 = 426 mL
