Access to HE Science - Chemistry help!!

I'm a complete loss and can't figure out a way to complete these problems! I have already attempted them but had a few sent back to resubmit and they're the ones I absolutely can't do!! Hoping someone out there is a chemistry genius and can shed some insight!


*A beaker contains 150cm3 of 0.25 mol dm3 sodium hydroxide NaOH solution.*

i) How many moles of sodium hydroxide are present in 150cm3?
ii) What mass of sodium hydroxide are present in the solution?


Hope somebody can help!
