PH question

[geffman1]

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?

 

[symbolipoint]

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'

 

[geffman1]

does that mean it dissociates completely?

Yes, you may safely assume it is completely dissociated.
