How much of a drug (in grams) with a molecular weight of 500 do I need to make 100ml of a 20mM solution?
8. Using two new investigational ingredients, agent X (molecular weight = 1205, dissociation factor = 2.6) and agent Y (molecular weight = 756, dissociation factor = 4.2), you are preparing a solution for an experiment as follows: Agent X 5.00 g Agent Y 5.00 g NaCl 7.75 g Distilled water QS to 1000 mL What is the freezing point of this solution? How much more NaCl do you need to make it isotonic? (20 Points) bambe to our boot boo...
How will you make a 1L of a 6M solution of sucrose? The molecular weight of sucrose is 342.2965 g/mol. If you start with the sucrose powder, how would you make this?
For live cell imaging, the PBS solution often contains 0.9 mM calcium chloride (molecular weight = 110.98) and 0.49 mM magnesium chloride hexahydrate (molecular weight = 203.3). For 1 liter of PBS, how much calcium chloride and magnesium chloride would you have to add to the standard PBS recipe? (Answer to 2 decimal places)
You are required to make a solution that contains 50 mmoles of buffer (its molecular mass is 121.1 g/mol), 300 mmoles of sodium chloride (its molecular mass is 58.44 g/mol), and 10% glycerol in a total volume of 0.75 L. Tell me (A) what weight of buffer and NaCl you will need, and (B) what volume of glycerol (diluted from a 100% stock concentration) you will need. Also, (C) what then makes up the additional volume to 0.75 L, and...
need help calculating mmol i have the molecular weight in (g/mol) i have the amount in volume (uL) MW(g/mol)- 112.22 volume (uL)- 400 im confused on how to calculate for mmol from those two set of information.
How do you prepare a 6 mM solution of zinc chloride in 0.1 M MOPS buffer? How do you know how much buffer to put in the solution for the desired final concentration? Same question for preparing a 0.4 mM solution of a peptide with molecular weight of 1565.8 g/mol in 0.1 M MOPS? I dont understand how the buffer can have a different concentration than final solution but be used to make the solution?
I am given the concentration of a substance in a solution (2.7 mg/100ml) and fhe molecular weight of the substance (180.158g/mol) how do i find the quantity in g of substance?
