how to calculate Standard Temperature & Pressure?

Question

calculate the volume in gas in liters of of 3.50 moles of gas at STP.

a. 1.27

b. 0.721

c. 541

d. 1.08 x 10^3 torr.

thanks steve g. i forgot to put letter e. which is. 78.4

Answer 1

PV = nRT

V = nRT/P

V = (3.50mol)(62.4L-torr/mol-K)(273K)/(760torr) = 78.4 L

Answer 2

that's completely in conformance with Avagadro. For any gases, as long as they are all on the comparable situations of temperature and tension, mols could be study as volumes. that's genuine decrease than all equivalent situations, no longer in basic terms at STP. occasion:( that's in undemanding terms theoretical, that the reaction is going to of entirety, which it would not.) N2+ 3H2 ? 2NH3 you are able to study this as: 1mol of nitrogen will react with 3mol of hydrogen to offer 2 mol ammonia. or you are able to the two wisely say: 1volume of nitrogen reacts with 3 volumes of nitrogen to offer 2 volumes of ammonia. tension and temperature are beside the point, as long as all 3 gases are on the comparable situations.
