Determine the minimum volume of 6.40M HNO3 required to dissolve a 2.40g sample of Cu.

2NO3-(aq)+8H+(aq)+3Cu(s)-->2NO(g)+4H2)(l)+3Cu2+(aq)

Convert 2.40 g Cu to moles. moles = grams/molar mass
Using the coefficients in the balanced equation, convert moles Cu to moles HNO3.
Molarity = moles/L. YOu know moles HNO3 and M HNO3, calculate L.
