Molarity (M) = (moles of solute) ÷ (liters of solution). To calculate the number of moles of a solute, you need two pieces of information, which you may have to infer from other data. The first is the chemical formula of the solute, and the second is the mass of the solute. Yo...
Step 3:Subtract the smaller number of moles from the larger number. Step 4:Divide the number of moles by the total amount of volume used to get the concentration. Step 5:Plug the concentration value into the correct formula and use it to calculate pH. ...
To determine the equivalent weight of NaOH, first it needs to be determined what type of substance it is. NaOH is a base; therefore, the n number of equivalents is the absolute value of the number of hydroxide ions. In this case, there is 1 hydroxide ion that dissociates in water. ...
Follow the stoichiometry - how many moles of NaOH reacted? I'm not sure I'm sorry I thought 1.It would be easier if you'd just explain the solution for me and I would understand it that way.Thanks It's better in terms of your learning if you come to the solution your self. What...
pH and pOH are linked with the following equation: pH+pOH=14 Answer and Explanation: To solve this question we must first find the number of moles, n(NaOH), of sodium hydroxide: {eq}n(NaOH) = c(NaOH) * v(NaOH) = 1.39 *......
The mass by volume percentage is used to measure the concentration of solution. It is denoted by % m/v.The concentration of solution is expressed as number of moles of solute present in a liter of solution. The mathematical expression for this is mentioned below: {eq}Mass \:b...
5.83 g magnesium oxide is dissolved in 20.0 mL of solution. Calculate the concentration (m/v) of magnesium oxide expressed as percent by mass. Solutions A solution has a limit to the number of solutes it can hold. This can be ex...
