Calculate the density of methanol ch3oh
WebMethanol is a promising energy carrier because, as a liquid, it is easier to store than hydrogen and natural gas. Its energy density is, however, lower than methane, per kg. … WebAnswer: Here we have the following data-- Methanol is CH3OH with molar mass of 32g. Now we have 2.45 molar solution which means there are 2.45 moles of Methanol per every litre of solution. Mass of Methanol in every litre= 2.45 X 32 = 78.4g Mass of every litre of solution = 976g (The Density is ...
Calculate the density of methanol ch3oh
Did you know?
WebMay 18, 2016 · Now, your methanol solution is said to have a molarity of #"0.00050 mol L"^(-1)#. This means that you get #0.00050# moles of solute per liter of solution. To keep the calculations simple, let's assume that you have a #"1-L"# sample of this solution. The first thing to do here is use methanol's molar mass to convert the number of moles to … WebTo find the percent composition (by mass) for each element in CH3OH we need to determine the molar mass for each element and for the entire CH3OH compound.We...
