( 1 atm = 101.325 Kpa )
* So we need a convert from Kpa to atm ..
*The solution:
15 x (210/101.325) = (790/101.324) x V
V = 15 x 2.073 / 7.797
V = 4.0 l
So the answer is [ b. 4l ]

Chemistry

The nucleus has an overall positive charge as it contains the protons. Every atom has no overall charge (neutral). This is because they contain equal numbers of positive protons and negative electrons. These opposite charges cancel each other out making the atom neutral.
