A 0.50 g mixture of Cu2O and CuO contains 0.425 g of Cu. The mass of CuO in g in the mixture is X. Cu=63.5 u, O=16 u Then the value of 10X up to the nearest integer.

Question

A $0.50 g$ mixture of ${Cu}_{2} O$ and $CuO$ contains $0.425 g$ of $Cu$ . The mass of $CuO$ $(in g)$ in the mixture is $X$ . $(Cu = 63.5 u, O = 16 u)$

Then the value of $10 X$ up to the nearest integer.
