   hey guys, ive just started PH, just wondering if you could show me how to do this question. thanks for any help
   
   What is the pH of a solution made by mixing 800 mL of 0.01 M HNO3 and 700.75 mL of water?

   Nitric acid is a strong acid - what does this mean?
   pH means "negative logarithm of the hydrogen ion concentration in Molarity", at least for practical purposes - Did you yet calculate the hydrogen ion concentration in your given solution?
   
   note: the logarithm is in 'base ten'

   does that mean it dissociates completely?

   Yes, you may safely assume it is completely dissociated.
