Question

Use the ideal gas law equation to find the gas constant in R.

 

Here is your data:

 

Patm = 760 mmHg

 

PH2O = 20 mmHg

 

mMg = 0.040 g, must be expressed in moles, so nMg = nH2 = 0.040 g / 24 g/mol Mg

 

mol Mg = mol H2

 

Volume of H2 = 41.0 mL

 

Must calculate the pressure of H2, express the Pressure in atm, Temperature in Kelvin and Volume in Liters.
