How many moles of h2o would be produced from 1.75 moles of o2 with unlimited c3h6

1.75 (moles O2) × 6 (moles H2O) ÷ 9 (moles O2) = 1.17 (moles H2O)

You have to convert moles of O2 into moles of H2O so it's the number of moles you start with (1.75 O2) × the number of moles from the element you want (6 H20), then ÷ by the number of moles that the element that you already have (9 O2).

What do you mean by that? like the contents? the thc level?

Idont know. if you want an answer you need to give us some context dude.
