2014年1月8日 · It depends on the substance whose volume you know. > If you have a pure liquid or a solid, you use its density to calculate its mass and then divide the mass by the molar mass. If you have a solution, you multiply the molarity by the volume in litres. MOLES FROM VOLUME OF PURE LIQUID OR SOLID There are two steps: Multiply the volume by the density to get the …

2024年5月24日 · How many moles are in 68.5 liters of oxygen gas at STP? 1 mole of any gas occupies 22.4 liters at standard temperature and pressure (STP). Therefore, 68.5 liters of oxygen gas at STP would be 68.5 ...

So, if you are given these values for temperature and pressure, the volume occupied by any number of moles of an ideal gas can be easily derived from knowing that 1 mole occupies 22.4 L. #V = n * V_(molar)# For 2 moles of a gas at STP the volume will be #2# #"moles" * 22.4# #"L/mol" = 44.8# #"L"# For 0.5 moles the volume will be

2024年5月20日 · To find the moles of sodium chloride in the solution, you can use the formula: moles = molarity × volume (in liters). First, convert 22.0 ml to liters by dividing by 1000 (22.0 ml ÷ 1000 = 0.022 L).

2018年6月27日 · The #"mole"# is simply the number of particles. And #"litres"# is a UNIT of volume. #"Density"="Mass of particles"/"Volume occupied by the particles"# CAN be related to the molar quantity, but this was not what you asked...

2024年6月6日 · To convert moles to liters for a gas at standard temperature and pressure (STP), you can use the ideal gas law. At STP, 1 mole of any gas occupies 22.4 liters. In this case, 4.50 moles of chlorine ...

2024年6月13日 · If that many moles is in 1000 liters, than the molarity (in moles per liter) is 4.108 ÷ 1000 = 0.0041 M. Is moles per liter the same as moles per cubic meter?

2016年3月7日 · First we assume a temperature and pressure; the molar volume at RT and 1 atm is 25.4 dm^3 mol^-1. We get a volume of slightly over 100 L. So all we have to do is multiply the number of moles by the molar volume: 4*molxx25.4 dm^3 mol^-1 or 4*molxx25.4 L mol^-1 (1L=1*dm^3) = ??" litres"

2014年5月25日 · The Molar Volume of an ideal gas at STP, which we define to be 0^@ "C" and "1 atm" arbitrarily (because we're old-fashioned and stuck in 1982) is "22.411 L/mol".

2024年6月2日 · Then, use the formula moles = Molarity x Volume (in liters) to find the number of moles of NaI. In this case, it would be 0.400 mol/L x 0.050 L = 0.020 moles of NaI. Related questions
