solve for y : y 2 = –2y + 2. solution: given, y 2 = –2y + 2 rewriting the given equation; y 2 + 2 y – 2 = 0 using quadratic formula, \(\begin{array}{l}y=\frac{-b \pm \sqrt{b^{2}-4 a c}}{2 a}\end{array} \) \(\begin{array}{l}y=\frac{-(2) \pm \...
How do you solve for mole fraction, density and %w/w, when you are given Cr2(SO4)3, with molarity of 1.26 M and molality of 1.37 m? Concentration Units: Both concentration units of molarity and molality are expressed in moles sol...
4. Convert to a Percentage Use the formulax= (c÷V) × 100 to convert the concentration (c) and volume (V) of the final solution to a percentage. In the example,c= 60 ml andV= 350 ml. Solve the above formula forx, which is the percentage concentration of the final solution. In...
I am known to be occasionally wrong. Re: How much Lt Oxygen in water «Reply #1 on:February 06, 2020, 03:59:02 AM » You can't use some randomly selected law to solve a problem that is described by another one. It won't ever work. But you are right mentioning Henry's Law,...
Molarityis one of the most common units of concentration. It is used when the temperature of an experiment won't change. It's one of the easiest units to calculate. You get the mass of solute for the solution, mix the solute with a known volume of solvent, and divide mass by volume ...
So to solve for 0.25 cubic meters: Answer in Liters = 0.25 m3* (1,000 L/m3) Answer in Liters = 250 L Method 3: The No-Math Way Or, easiest of all, you could just move the decimal point 3 places to the right. If you're going the other way (liters to cubic meters), then...
