To prepare a 10ml solution containing 1 mole of BSA (Molecular weight 66000 g/mol), you would need 66g of BSA. To prepare a 100ml solution containing 1 mole of BSA, you would need 660g of BSA. Remember to adjust the volume accordingly after dissolving the BSA to ensure accurate concentration.
To prepare a 500 micrograms per milliliter (µg/mL) solution of BSA from a 1 mg/mL solution, you will need to dilute the original solution by a factor of 2. Start by measuring out 0.5 mL of the 1 mg/mL BSA solution and then add it to a total volume of 1 mL. This will result in a final concentration of 500 µg/mL.
just took 0.1g phenolphathlein in 50ml of ethyl alcohol and make the solution up to 100 ml
Proportionally you will need 1 and 1/2 mg of salt.
You add 9.09ml of stock solution to a volumetric and make it up to 1 litre to get a 110 dilution

If we add 1 L of water to 1 L of 2 M NaCl solution will give 2 L of 1 M NaCl solution
6.023 X 1023 particles make up a 1M solution.

1 will dissolve to make a solution, 1 won't.
Proportionally you will need 1 and 1/2 mg of salt.
1% solution of KOH contains 1g of KOH in 100g of solution. This means that you need to mix 1g of KOH and 99g of water.
What volume of this solution do you desire? Let's say you want to make 1 liter of such a solution. You would weigh out 1 gram (1000 mg) of NaCl and dissolve it in enough water to make a final volume of 1 liter (1000 ml). Since 1000 ppm means 1000 mg/liter, this is how you make 1 liter of that solution. For larger or smaller volumes, adjust appropriately.
