D. details about what happening
(4) PCl5--> PCl3+ Cl2 is the correct answer because we both have 1 P atom and 5 Cl atoms on both sides, and thus the masses of the elements don't change.
Hope this would help~
Hope it helps! (: - stoich right?
Hey there!
Volume in liters:
85.75 mL / 1000 => 0.08575 L
Therefore:
C = m / V
1.27 = m / 0.08575
m = 1.27 * 0.08575
m = 0.1089 g
hope this helps!
