A gas cylinder of N2 has a volume of 49.6 L. At 35 °C the pressure is 24.6 atm. How many g of N2 are in the cylinder? (R = 0.0821 L•atm/mol•K)

If a solution is considered basic, then a) the hydroxide ion and hydronium ion concentrations are equal. b) the hydroxide ion concentration is less than the hydronium ion concentration. c) the hydronium ion concentration is greater than the hydroxide ion concentration. d) the hydroxide ion concentration is greater than the hydronium ion concentration.

How will the volume of a gas be affected if the pressure is tripled, but the temperature remains the same?
