Answer:
248 mL of 5% w/v boric acid solution should be used to obtain the solution needed.
Explanation:
We can calculate the volume of the 5% w/v boric acid solution needed to prepare the buffer solution 1.24% w/v using the following equation:
Where:
: is the concentration of the initial solution = 5% w/v
: is the concentration of the final solution = 1.24% w/v
: is the volume of the initial solution =?
: is the volume of the final solution = 1 L
Hence, the volume of the 5% solution is:
Therefore, 248 mL of 5% w/v boric acid solution should be used to obtain the solution needed.
I hope it helps you!
Answer:nothing beats the chemistry between us :) smooth right?
Explanation:I’m pretty sure u have to show the part before the questions so that people can respond to it since there is no info on how to answer the question :p
The degree of compactness of a substance
Diatomic molecules are molecules composed of only two atoms, of either the same or different chemical elements. The prefix di-is of Greek origin, meaning "two". If a diatomic molecule consists of two atoms of the same element such as hydrogen (H2) or oxygen (O2), then it is said to be homonuclear.
