Question

a 2.747g sample of manganese metal is reacted with excess HCl gas to produce 3.24L of H2 at 366K and .927atm and a manganese chloride compound(MnCl0. What is the formula of the manganese chloride compound produced in the reaction?

Answer 1

I hope you made a typo and the (MnCl0 you wrote you intended to be (MnCl). Otherwise, where is the oxygen coming from?

Answer 2

i did have a typo sorry it is MnCl

Answer 3

Convert g Mn in the reaction to mols.

Use PV = nRT to calculate mols H2.

Use those two numbers to determine the formula. You should obtain MnCl2.

Answer 4

Scratch that answer of MnCl2. It may not be that at all.
