Need help in primer dilution?

Hello, I don’t know how I need to do a dilution primer…

The liophilizated concentration primer is 32.2 nmol and the concentrations is 100 uM the report say:

to 100 pM/ul dissolve in (ul) 320 ul of DDW…I need to keep the 0.36 uM work solution. I used the formula to calculate Cnewx Vnew = Cstock x V stock and if I calculate right I need to add 115 to 1000ul is correct what I say or I wronged in my calculi?

Kindly help…

Thanks
