an air compressor has a 10.27 cylinder under a pressure of 6.476 atm at 40.3 degrees celcius. calculate the number of moles of air in the tank

Ithink the answer is d

According to arrhenius theory of acid and bases, an acid is a proton donor, while base donates hydroxyl ions. further, acid and base reacts to form salt and water.consider following example.hcl    +      h2o          →      cl-          +      h3o+here, hcl has donated a proton, hence it is an acid.now consider following reactionhcl      +      naoh            ↔      nacl      +        h2oin this reaction, hcl donates proton, hence it is acid. on other hand, naoh donates hydroxyl ion (i.e. hence it is a base.   

Number of molecules=(12.01+2x15.9994)/112 x na
