Hi, so to solve for this, we need to calculate first the number of moles of h2o produced using the number of moles of the reactant c2h4.
00:11
If we have 6 .30, this is moles of c2h4, convert this to h2o or moles of h2o by multiplying the stoichiometric ratio.
00:22
As per balance equation, for every 1 mole of c2h4 reacted, it will produce 2 moles of water h2o.
00:31
So that means we could cancel moles of c2h4 and this will give us 12 .6, this is moles of h2o.
00:40
And we're calculating the volume of water at stp.
00:44
Remember that stp stands for standard temperature and pressure and the temperature here is equivalent to 273 .15 kelvin and the pressure is equivalent to 1 atm.
00:56
Therefore, we could use the ideal gas equation pv is equivalent to nrt to solve for the volume.
01:02
Rearranging this, we'll have nrt over the pressure...
