Questions and Videos on Dilution Calculations, within Chemistry

Here's my take on this. Assuming that the question is not incomplete, your goal here is to figure out the dilution factor, "DF", for the second dilution, and the overall dilution factor for the two …

Cost of a Rose = $3 Cost of a Carnation = $1 Cost of a Tulip = $1 Let roses be denoted by x, carnations byy and tulips by z. Given that: 3x_1 + 2 y_1 + 1 z_1 = $14-------equation(1) 6 …

It looks like a serial dilution is in order. How about this? Step 1: Dissolve 40 mg of "Lis" in 100 mL of water. " [Lis]" = (40 × 10^"-3" color (white) (l)"g")/"0.100 L" = "0.40 g/L" Step 2: Dilute 1 mL …

Multiply the number that you got in the previous step by the inverse of the number on your dilution tube. For example, if the plate you selected was the 10^-2 plate, you would multiply 10 by …

Oct 7, 2017 · 4√5 is also expressed as 4 times √5, or 4 ⋅ √5. If you were to type √5 in your calculator, you would get a value of 2.2360679775. Then, take this and multiply it by 4 to get …

Here's how you could do that. For starters, you can only dilute the original solution by adding water, the solvent. In any dilution, the amount of solute remains constant. So, your starting …

125 full bottles It is a matter of how many 28's will fit into 3500 ->3500-:28 By calculator this gives: 3500-:28=125 But suppose you do not have a calculator.

Now that we know the value of all three angles and the length of side #c# we can find the lengths #a# and #b# using the Law of Sines: #color (white) ("XXX")a/ (sin (A))=b/ (sin (B))=c/ (sin (C))# …
