This law brings Boyle's, Charle's, Avogadro's, and Gay-Lussac's laws together in one neat, easy to use package: PV = nRT. Using
simple algebra any of this variables can be isolated: P = nRT/V, V = nRT/P, T = PV/nR, n = PV/RT, or the ideal gas constant R computed. All gas calculations must be made using temperatures in Kelvin. If the ideal gas constant R = 0.08206 L∙atm/mol∙K, what volume will 1.00 mol of a gas occupy at 1.00 atm of pressure and 273 K?
this is fairly simple if you have a periodic table with you.
Explanation:
atomic number 17 is Cl mass numer is 35.45 for protons neutron and electron you can just look that up on google. atomic number is where it is at on the periodic table and the mass number is in the little square at the bottom.
