Help me find my percent yield for my witting reaction experiment....

The weight of my final product was: 0.13
I put 0.40 g of benzyltriphenylphosphonium chloride, 0.23 g of 9-anthraldehyde and 1.0ml DMF and 0.5ml of aqueous sodium hydroxide into the flask at the start of the experiment
How do I get a percent yield from this data???
8ml of a mixture of 1:1 propanol and water was also added... Idk if that's important
benzyltriphenylphosphonium chloride mol weight is 388.88
9-anthraldehyde mol weight is 206.24


In my book it also says the density of sodium hydroxide 50% is 1.5 gml
After filtration my product was 0.23
My FINAL product was 0.13

See your post above.
