Calculating H2/Mg Ratio in Magnesium & HCl Lab

Click For Summary

Discussion Overview

The discussion revolves around calculating the average ratio of grams of hydrogen gas produced per gram of magnesium in a laboratory setting involving the reaction between magnesium and hydrochloric acid. The focus is on the conversion of hydrogen gas volume to mass to facilitate this calculation.

Discussion Character

  • Homework-related

Main Points Raised

  • One participant requests clarification on how to convert the volume of hydrogen gas produced into moles.
  • Another participant suggests using the ideal gas equation for the conversion from volume to moles.
  • A participant notes the lack of experimental data provided in the original post, indicating that the question is not fully clear without this information.

Areas of Agreement / Disagreement

There is no consensus on the calculation process due to the absence of specific experimental data, and participants are exploring methods to address the problem.

Contextual Notes

The discussion highlights the need for specific experimental values to perform the calculations accurately, as well as the assumptions involved in using the ideal gas equation.

Homework Statement



Calculate the average ratio of grams of hydrogen gas produced per gram of magnesium. This is part of a lab in which I know how many grams of magnesium were used and how many ml of hydrogen gas was produced

Homework Equations



Mg (s) + 2 HCl ---> MgCl2 + H2

Well, you have not posted any experimental data, so the question - as posted - doesn't make much sense.

Convert hydrogen volume to number of moles, number of moles to mass.
 
how do you convert volume to moles
 
Use ideal gas equation.
