Gas Laws Conclusion

As we heated the water inside the beaker in order to evaporate our liquid solution into a gaseous form, we had to be very careful with our measurements of the solution.
What we did is by boiling water around an Erlenmeyer, we heated an unknown solution until the water boiled giving us the sign that our solution was now in gas form. Taking
out the Erlenmeyer, what we then did is weighed the flask with the gas inside and subtracted from the mass of only the flask which we measured earlier. The new mass of
the gas was a significant part of the lab which would later allow us to evaluate the molar mass of the substance. After getting the constants, like the barometric pressure measured in class, along with the constant R, and the volume of the flask, we could solve for the molar mass by multiplying all the variables except barometr...
