The balanced chemical equation for the reaction between PCl5 and water is given below. If 3.45 moles of HCl are produced, how ma
enyata [817]
The coefficients of the substances give you the ratio of the number of moles.
The 4 before the H2O and the 5 before the HCl tell you that for every 5 moles of HCl created, 4 moles of H2O had to react.

Therefore:
(3.45mol HCl)(\frac{4 mol H2O}{5 mol HCl})
can be used to find the moles of H2O that react.

(3.45mol HCl)(\frac{4 mol H2O}{5 mol HCl}) = 2.76 mol H20

damaskus [11]
Mass = 63.5 grams

density = 0.818 g/mL

D = m / V

0.818 = 63.5 / V

V = 63.5 / 0.818

V = 77.628 mL
