If you were asked to prepare 150𝑚𝑙of 8%﻿agarose, how many grams agarose would you weigh out?

Accepted Answer

∻Answer∻ ⚹ You would weigh out 12 grams of agarose. ⚹ ∻Solution∻ ‖ a ⋮ Calculate the mass of agarose needed using the percentage concentration formula: $$ \text{mass of agarose} = \text{volume} \times \text{percentage concentration} $$ ‖ ‖ b ⋮ For 8% agarose gel, the calculation is: $$ \text{mass of agarose} = 150\,ml \times \frac{8}{100} $$ ‖ ‖ c ⋮ Convert the volume from milliliters to grams (assuming the density of water is 1 g/ml, which is a common approximation used for these calculations): $$ \text{mass of agarose} = 150\,g \times 0.08 = 12\,g $$ ‖ ∻Key Concept∻ ⚹ Percentage concentration ⚹ ∻Explanation∻ ⚹ The percentage concentration formula is used to calculate the mass of a substance needed to create a specific volume and concentration of a solution. ⚹◊What is the formula to calculate the amount of agarose needed to prepare a certain percentage solution?⍭ Generate me a similar question◊
