How many grams of CuSO_4 * 5H_2O are needed to prepare 100 …
2016年3月11日 · Now you have to determine how many grams of copper(II) sulfate pentahydrate would contain this many grams of copper(II) sulfate. To do that, calculate the hydrate's percent composition by using its molar mass and the molar mass of anhydrous copper(II) sulfate. Remember that there are #color(red)(5)# moles of water for every #1# mole of hydrate
What is the percent by mass of water in CuSO_4*5H_2O? - Socratic
2017年4月3日 · %"water"="Mass of water"/"Mass of copper sulfate pentahydrate"~=36% %"water"=(5xx18.01*g*mol^-1)/(249.68*g*mol^-1)xx100%~=36% This video provides a detailed ...
Question #b171f - Socratic
2014年7月29日 · O.K., you can do this. It just takes thinking about it in a little different way than you are, perhaps, used to: First, you need to know how much copper(II) sulfate pentahydrate you have got to start with. You know that the total mass is 14.98 grams, and that of that 14.98 grams, 10.00 grams is the mass of the crucible. So..... Right! the mass of the copper compound is 14.98 - …
How do you calculate the percentage composition of Copper in
2016年3月26日 · "Molar mass of copper"/"Molar mass of copper sulfate" xx100% (63.55*g*mol^-1)/((63.55+32.06+4xx15.999)*g*mol^-1) xx100% = ?%
What is the formula mass of CuSo4? - Socratic
2018年2月23日 · I'm not sure what the formula mass is, but I'm guessing that you are talking about molar mass. To find the molar mass of CuSO_4, we must take all of the elements in the molecule, and add their molar masses together. Cu or copper has a molar mass of 63.546 \ "g/mol". S or sulfur has a molar mass of 32.065 \ "g/mol". O or oxygen has a molar mass ...
Calculate the mass of "CuSO"_4 * 5"H"_2"O" needed to prepare
2018年4月16日 · Here's what I got. For starters, you know that "0.05000-mol L"^(-1) solution of copper(II) sulfate contains 0.05000 moles of copper(II) sulfate, the solute, for every "1 L" = 10^3 quad "mL" of the solution. This means that your sample must contain 100.00 color(red)(cancel(color(black)("mL solution"))) * "0.05000 moles CuSO"_4/(10^3 color(red)(cancel(color(black)("mL solution")))) = "0.005000 ...
How do you calculate the molar mass of copper II sulfate …
2024年6月3日 · What mass of anhydrous copper 2 sulfate can be obtained by heating 125g of cuper 2 sulfate pentahydrate? To find the mass of anhydrous copper(II) sulfate obtained: Calculate the molar mass of each ...
Question #b0054 - Socratic
2015年4月23日 · The mass of the hydrate was 11.3 g. The same idea you've used to determine the formula of a hydrate applies in this case, only this time you'll have to work backwards from the formula to determine the mass of the hydrate. So, you know that you're dealing with copper (II) sulfate pentahydrate, CuSO_4 * 5H_2O. As you can see, for every 1 mole of anhydrous copper (II) sulfate, you get 5 moles of ...
What is the molar mass of copper (ll) sulfate? - Socratic
2016年5月12日 · Perhaps you should tell us. CuSO_4 is composed of Cu, 63.55*g*mol^-1, S, 32.06*g*mol^-1, and oxygen 4xx15.999*g*mol^-1. So what is its molar mass? The dissolution of white, anhydrous CuSO_4 in water is a truly beautiful chemical reaction. Beautiful, macroscopic crystals of CuSO_4*5H_2O can be grown whose colour is truly magnificent. Here is a video discussing how to find the empirical formula ...
What is the weight of an anhydrous solvent required to make
2017年11月9日 · a. approx. 25*g "Moles of cupric ion" = (10*g)/(63.55*g*mol^-1)=0.157*mol. And thus [CuSO_4](aq)-=0.157*mol*L^-1 And in a one litre volume there is a mass of.... 0.157*mol*L^-1xxunderbrace(159.61*g*mol^-1)_"molar mass of copper sulfate"=25.12*g WITH RESPECT to CuSO_4. b. if we started with the pentahydrate we would take the product... 0.157*mol*L^-1xxunderbrace(249.69*g*mol^-1)_"molar mass of ...
