In an electrolysis experiment, 15.0 g of water are decomposed by means of an electrical current to form gaseous hydrogen and oxygen. Calculate the volume of gaseous hydrogen produced at 25 °C and 100 kPa.
Note:
Always write down the balanced chemical equation.
Moles: 15/2 x1 + 16 = 15/8= 08333
PV= NRT
V= NRT/P
(0.8333)(8.314)/100
V= 20.64L
Where does this person get 8.314 from?
How does .833 x 8.314 / 100 = 20.64?
