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...
Molarity is used for expressing the concentration of the solution. It is defined as the number of moles of solute dissolved in a liter of solution.Answer and Explanation: Given, Molarity of solution = 1.50 M Volume of solution = 100 ml = 0.100 L Molar mass of NaCl = 58.5 g/mol ...
Osmolarity | Definition, Units & Calculations from Chapter 1/ Lesson 20 74K Study the osmolarity formula and osmolarity units. Learn how to calculate osmolarity. See the difference between osmolarity and molarity. Related to this Question What percent NaCl solution...
Since HCl is a strong acid, it completely ionizes, and the pH of HCl in solution can be found from the concentration (molarity) of the H+ ions, by definition equal to 0.100 M. (The conjugate base of the acid, which is the chloride ion Cl–, would also have a concentration of 0.100...
It helps to write out the conversion and make sure units cancel. You might want to draw a line through them in complex calculations to keep track of active units. Watch yoursignificant figures. Chemistry professors are unforgiving when it comes to reporting an answer, even if you set up the...

molarity. A logarithm of a number is simply the exponent when you write that number as a power of ten. The definition of pH solved for hydrogen ion molarity is then [H+] = 10-pH. For example, the molarity of hydrogen ions in a pH 6 solution is 10-6M. Use this calculation to ...
Use the density of water to determine the mass of water per unit volume. Thedensity of wateractually varies depending on conditions (cold water is denser; warm water is less dense), but the value typically used in calculations is 1.00 gram per milliliter (1 g/mL). In other words, 1 mi...
