405.218 moles

Explanation:

It is a 0.815 M solution, so that means that in 1 litre you have 0.815 moles of solute.

Therefore in 497.2 litres of the solution you have 497.2 x 0.815 = 405.218 moles of solute.

(By the way, the correct terminology is "0.815 M sodium cyanide solution" - saying "0.815 M sodium cyanide" is meaningless).
