# Mass Atomic - Chemistry

A metal $$\ce{X}$$ is reacted with hydrochloric acid according to the balanced equation:

$\ce{X}(s)+\ce{3HCl}(aq)\rightarrow\ce{X}^{3+}(aq)+\ce{3Cl-}(aq)+\frac{3}{2}\ce{H2}(g)$

If 500 mL of a 3 M solution of hydrochloric acid react completely with 26.0 g of this metal, what is the atomic mass of $$\ce{X}$$?
