Write down the recipe to make 50 ml of 10x pbs.
00:09
So the 10x pbs has this protocol.
00:14
Let's say this is data protocol, which we want to make one liter.
00:18
So let's write down this recipe first with one liter, and we can convert it to 50 ml.
00:23
So if we want to make one liter, we know that we need 25 .6 gram of sodium phosphate.
00:35
Oh, actually, disodium phosphate.
00:39
So 25 .6 gram of disodium phosphate times seven water, 80 gram of sodium chloride, 2 gram of potassium chloride and 2 gram of potassium phosphate.
01:13
So this is out of 1 liter.
01:22
Now the question asks us to make a 50 milliliter.
01:25
So now we know that 1 liter is 1000 milliliter...
