Web15 mrt. 2024 · Calculations involving the mole can be used to determine unknown concentrations, volumes and masses in reactions. One mole of any gas occupies 24 cubic decimetres at room temperature and pressure. WebNow, the next question is how many molecules is that? Well, we know that each mole has roughly 6.022 times 10 to the 23rd molecules in it, so we just have to multiply this times 6.022 times 10 to the 23rd. So, we could write it this way. We could write 0.0761 moles, …
Web20 apr. 2024 · Therefore the number of moles present in Argon is 0.20 moles. Explanation: Mole: The mass of a substance containing the same number of fundamental units as there are atoms in exactly 12.000 g of . Given: volume (v) = 4.7 litres. Volume of argon at STP conditions = 22.4 litres. To find: volume of argon at STP conditions. We know; n = where; WebI believe it is because the differential in temperature change (296K to 229K) is countered by the much larger change in pressure (765Torr to 6.51Torr) and therefor you still get a large increase in volume even with one of the variables counteracting that increase. P1(765Torr) * T2(229K) is a much larger number than P2(6.51Torr) * T1(296K).
