Consider three 1 l flasks at stp. flask a contains nh3 gas, flask b contains no2 gas, and flask c contains n2 gas. which contains the largest number of molecules? in which flask are the molecules least polar and therefore most ideal in behavior?

1 mole of gas occupies 22.4 L at STP. Therefore, each gas has 1/22.4 moles and because the number of moles is the same, the number of molecules of each gas is also the same.

The least polar molecules are of N₂ and they will show the most ideal behavior out of all three of the gases. 

The independent variable is the type of music.the dependent variable is the pulse rate.the intervening variable is the age of the subject.if the mother does not like rock, her pulse is likely to not increase.the same might be true for the sister.the friend may like rap and gets excited.to establish cause/effect relationship, all of the subjects must be consistent.hope i .
