Answer from: divaughn1906

First, we need to find out how many moles we have of $Cu ( NO_{3} )_{2}$ if we are given 6.35g.

We need to calculate the molar mass of the molecule:

Cu: 63.546g
N: 14.01g * 2 = 28.02g
O: 15.999g * 6 = 95.994

Add them together to get: 187.56g

So now we need to find the number of moles we are given. This can be done by setting up a multiplication equation and cancelling the units:

$\frac{1mole}{187.56g}* \frac{6.35g}{1}=0.034 mol _{Cu( NO_{3} )_{2} }$

So now that we know the number of moles that we have, we can use the molarity equation to find the volume of the solution. The molarity equation is:

$Molarity= \frac{moles}{Liters}$

So since we are given the molarity in the equation (0.750 M), we can plug in the molarity and moles to find the volume of the solution:

$0.750= \frac{0.034mol}{volume(L)}$

volume(L)=0.04533L

So now we know that the volume is 0.04533 Liters; however the question asks for the answer in milliliters. To do this, we must multiply by 1000:

$\frac{0.045L}{1} * \frac{1000mL}{1L}=45.33mL$

So the volume of the solution (in mL) is 45.33 mL.

two years ago, when picking flowers in the mountains back of yosemite valley, i found a book. it was blotted and storm-beaten; all of its outer pages were mealy and crumbly. the paper seemed to dissolve like the snow beneath which it had been buried, however; many of the inner pages were well preserved. and although all were more or less stained and torn, whole chapters were easily readable. this is the condition of the great open book of yosemite glaciers today; its granite pages have been torn and blurred by the same storms that wasted the castaway book.
