Using the ideal gas law, find the number of moles of Argon gas in a 5L tank at 20C and 3160kPa of internal pressure. R = 8.314 (kPa xL / (Kx mol))

O 3 mol
O 4.1 mol
O 6.5 mol
O 20 mol
O 2436 mol

fe 55.85 g/mol and h2o 18.02 g/mol.

gold is my favorite solid.

answer: option (a) is the correct answer.

explanation:

the measurement of hydrogen ions in a solution is known as ph.

if ph of a solution is less than 7 then the solution is acidic. if ph of a solution is greater than 7 then the solution is basic.

when the ph of a solution equals 7, then the solution is considered as neutral.

the ph of pure water is 7, therefore, it means that concentration of hydronium ions equals that of hydroxide ions.
