In chemistry, n molecules of an ideal gas have pressure (p), volume (v), and temperature (t) that stand in the following relation, where r is a constant. solve the equation for n, the number of molecules. pv= nrt

the answers are in the images, i received 100% on this assignment. hope this !

answer: x=60

none.

step-by-step explanation:

m1=5,m2=0

compare the two slopes in the decimal form. if the slopes are equal, then the lines are parallel. if the slopes are not equal, then the lines are not parallel.
