Answer: 0.25 mole PH3
Explanation: 1 mole of PH3 is equal to its molar mass P= 31 , H 1x3 = 34g
Solution:
8.5 g PH3 x 1 mole PH3 / 34 g PH3
= 0.25 mole PH3
It's one for ideal gases . by the way , remember that it's molar volume not volume itself and, this ratio is shown by Z and is called<span> Compressibility </span> factor.
