Approx. 190*g... By definition, rho, is given by the quotient.... rho_"density"="mass"/"volume", and thus has units of g*mL^-1-=g*cm^-3... And so we simply rearrange ...
May 15, 2017 · 36 neutrons. One way we have of differentiating between various nuclides of the same element is by writing the name of the element followed by a hyphen and the mass number of the nuclide. In your case, ...
Mar 28, 2016 · Explanation: Given point #-> (x,y)-> (-3,10)# Given gradient #" " (m) =-2# Thus #y=mx+c" "# becomes #" " y=-2x+c# '~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ #color (blue ...
The molarity of this solution is 0.25 mol/L. The molar mass of sucrose C_12H_22O_11 is 342 grams: (12 xx 12 + 22 xx 1+11 xx 16)=342 If we divide the given mass (85.5 g) by this molar mass, we get the number of moles o...
It is not the best form for good communication. Other than the specific "rules" of grammar in any language, what is "right" for writing is very flexible. In this example however, there are both too many long sentences...
Explanation: We're asked to find the molarity of the #"NaOH"# solution given some titration values.
Feb 13, 2018 · Try significant digits. You answer is correct. But the significant figures of your answer might not. Double check the way the numbers are written down in the original question. Is 2m written as 2.0m, 20...
Here's how you could do that. For starters, you can only dilute the original solution by adding water, the solvent. In any dilution, the amount of solute remains constant. So, your starting solution is 83%"v/v", which...
Lustrous Malleable Ductile Good conductors of heat and electricity These are four primary characteristics of metals, but there are many others as well. Metals tend to exhibit luster; that is, they appear to "shine" du...
See a solution process below: Let's call the number of weeks we are looking for: w We can then write a formula: $145 + $36w = $433. And we can now solve for w: First, subtract color(red)($145) from each side of the eq...
