Question

How many grams of MOPS powder have to be weighed and dissolved in the volume calculated in question 20 to make a 1 M solution?

Question 20
What is the molarity in mM of the base form of MOPS in a 500 mM MOPS buffer at pH8?

Answer 1

The question gives insufficient data to provide a direct numerical answer for the mass of MOPS powder needed. Knowing the molar mass of MOPS, the volume in liters for a 1 M solution, and using the formula mass (g) = moles x molar mass (g/mol), the required mass can be calculated.

Step-by-step explanation:

To calculate the amount of MOPS powder needed to make a 1 M solution, you need the molar mass of MOPS, which is not provided in the question. Assuming you have the molar mass, the calculation will be straightforward. First, determine the number of moles required for your desired volume of solution. Since the desired concentration is 1 M (1 mole per liter), the number of moles needed is equal to the volume in liters.

Then, multiply the number of moles by the molar mass of MOPS to get the mass in grams that needs to be weighed out.
