It doesn't matter how you work this out - it is the result that is important. Either: If the molecules are escaping easily from the surface, it must mean that the intermolecular forces are relatively weak. That means that you won't have to supply so much heat to break them completely and boil the liquid. The liquid with the higher vapour pressure at a particular temperature is the one with the... If you knew the volume of the liquid inside the container, you could run a couple of calculations based on density and conversions. For instance, if you had a pint of water in a container, you could figure out that the water weighed about a pound (water is easy to work with.)

(given volume/mol- find density) If a gold ring has a volume of 7.50 mL and contains 0.736 mol of Gold determine the density of Gold. You are given the volume in mL so you must find the mass!... How to work out the molar fraction, XA (XB etx) for a mixture? XA = nA/n . What assumptions are made when using the ideal gas law? The molecules have no volume (the volume of the molecules is negligible compared to the volume of the container) The molecules do not interact (the time during interactions is negligible compared to the time between them). How to calculate the compression factor, Z

Abstract Did you know that you can figure out how much sugar is in a liquid without ever tasting it? In this science fair project, you will learn how to measure the concentration of sugar dissolved in a liquid by using a laser pointer, a hollow prism, and some physics. how to make laxatives work better Exercise: 1. To calculate the excess volume, V E, from equation (6), it is necessary to calculate V m,A and V m,B, which represent the molar volumes of water and ethanol, respectively, and x A and x B, which represent the corresponding mole fractions of water and ethanol.

## How To Work Out Mol Of A Liquid

28/05/2008 · There is no simple conversion to go from mL to moles. mL is a unit of volume and moles is an amount of substance. However, if you know the density and molecular weight of the substance you can do the conversion.

- To determine the factor to convert one to the other we again need to work out the molecular weights. Ba(OH) 2 is 171 (ba=137) and Ba(OH) 2 .5H 2 O is 261 so the conversion factor is either 171/261, 0.66 for crystalline to anhydrous and 261/171, 1.53 for anhydrous to crystalline.
