Question

Volume and Moles 6 of 15 > Review Constants Periodic Table Avogadro's law states that the volume, V. of a gas is directly related to the number of moles of the gas when temperature and pressure are constant (Figure 1) Part B Vi Figure A sample of gas in a cylinder as in the example in Part A has an initial volume of 560 L and you have determined that it contains 1.50 moles of gas. The next day you notice that some of the gas has leaked out. The pressure and temperature remain the same, but the volume has changed to 140 L How many moles of gas (n) remain in the cylinder?

Answer 1

According to avogadro's Law 7 Initial Volume (1) = 56 L mitial moles (1,2= 1.6 moles final volume (V₂) = 14 L final moles (12) = ? V2 x ni moles 144 1.6 - 56 * Ng = 0.4 moles]
