How much money is 50 euros?

It's 50 euros.

Or about 407 yuan. Or 2083 rubles. Or 246 shekels.

Given that you just state 'money' and seem unaware that there are lots of currencies around the world, I assume that you are an US citizen. So it's about 65$ for you.

(And no, I'm not trying to imply that Americans are implicitly stupid, but stupid people on the net are most likely to come from the US.)
