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 ...
the molarity of a 0.6 moles of NaCl dissolved in 0.45 liters is 1.33 M (0.6 mol ÷ 0.45 L). Do this for both substances to let you calculate the final concentration of the solution. (Remember
Molarity is a familiar way to express concentration in chemistry. Take the number of moles, which is obtained from the molar mass, and divide by the number of liters. Normality takes into account reactive equivalents. The normality formula is N = Mn, wer
How to choose an indicator for an acid-base titration? What is a redox titration in chemistry? How to calculate the molarity of a solution In a titration of a sample of HCl(aq) with 0.113 M NaOH(aq), it took 51.2 mL of the base to reach the endpoint of the titration. Calculate the...
How do you calculate a weighted average in chemistry? Explain the concept of molarity and how to calculate it. Calculate the mass in grams 2.6 \times 10^{22} SO_2 molecules. Express your answer using two significant figures. Convert 8.70 um (micrometer)/s to km/hr using 3 significant fi...
If I made a 4.97 M solution with 2.16 mL of solute, what is the mol of volume, in liters? How do you solve gas stoichiometry problems? How do you convert liters to moles? For example, 75.2 L SO2 = moles How does 500 mL equal 0.500 kg?
You can rewrite the equation to solve for mass: mass = volume x density Densityof liquids usually is expressed in units of g/ml. If you know the density of a liquid and the volume of the liquid, you can calculate its mass. Similarly, if you know the mass and volume of a liquid, ...
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 \...
