Hello,
Can someone help with why my actual yield is so far off?
I combined .00813g of Mg ribbon with excess HCL and that produced 17mL of H2 gas.
Theoretically, I should have gotten 7.48 mL.
Mg + 2HCl --> H2 + MgCl2
I didn't run this reaction at STP .. but that should only account for less than 20% of the error. I double checked the mass. Can anyone see something obvious that I'm missing???
Thanks,
Josh
