WebThe number of liters of gas per mole. Strategy and Solution. We are asked to find the number of moles per cubic meter, and we know from Example 2 that the number of molecules per cubic meter at STP is 2.68 × 10 25. The number of moles can be found by dividing the number of molecules by Avogadro’s number. We let n stand for the … WebAt 15 degress celsius, you need more moles (56.3 moles instead of the 54.4 moles) to reach 23.8 mm Hg because the molecules have lower kinetic energy. That does not mean, that at 15 degrees, the equilibrium point (vapor pressure) is still 23.8 mm Hg. At 15 degress the vapor pressure of water is 12.8 mm Hg. So that does agree with your intuition. Webn1 = 0.40 moles n2 = 0.40 + 0.60 = 1 mole (because it says a person ADDED 0.60 moles to the already blown ballon, thus we must add 0.6 to the original amount) 2) Plug the amounts into Avogadro's Law equation, and solve for V2 V1n1=V2n2 1000.4=V21 V2 = 250 L The new volume of the balloon is 250 L!
