Calculating H2/Mg Ratio in Magnesium & HCl Lab

AI Thread Summary
To calculate the H2/Mg ratio in the lab experiment, first convert the volume of hydrogen gas produced into moles using the ideal gas equation. Then, determine the mass of hydrogen gas from the number of moles. Finally, divide the mass of hydrogen by the mass of magnesium used to find the average ratio. Providing specific experimental data is essential for accurate calculations. This method will yield the desired H2/Mg ratio for the lab report.

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.

TL;DR Summary: cannot find out error in solution proposed. [![question with rate laws][1]][1] Now the rate law for the reaction (i.e reaction rate) can be written as: $$ R= k[N_2O_5] $$ my main question is, WHAT is this reaction equal to? what I mean here is, whether $$k[N_2O_5]= -d[N_2O_5]/dt$$ or is it $$k[N_2O_5]= -1/2 \frac{d}{dt} [N_2O_5] $$ ? The latter seems to be more apt, as the reaction rate must be -1/2 (disappearance rate of N2O5), which adheres to the stoichiometry of the...
