mixing gas/oil

I have 2-cycle oil and 2 gallons of gas how much oil do i mix for 2 gallons of gas i have a 47cc cag MT-A1 is there a sertian amount i need to mix if so can u tell me?

roughly 160ml of oil to a gallon or 200ml to 5 ltrs this gives you a 25:1 mix

most bottles of 2 stroke have a mixing chart on the back if not do a search on the net for 2 stroke oil fuel mixture ratios
