I own 33.0 in money, so please, I hope to know how much the Zakat on this money is?

If the wealth reaches the nisaab and a (full) year has passed over it, then zakat of a quarter of a tenth (2.5%), meaning 825 riyals, becomes obligatory on it. The nisaab for zakat is the equivalent of 85 grams of gold or 595 grams of silver. If the wealth does not reach the nisaab or a (full) year has not passed over it, then there is no zakat on it.
