ibuprofen, c13h18o2, is a common medicine for treating mild pain, fever, and inflammation. a concentrated stock solution of 0.021 mg ibuprofen in 1.00 ml water is prepared. how many ml of water should be added to this solution to achieve a 3.75 μm solution of ibuprofen?

26.2ml

Explanation:

This is a delusion calculation. But before performing the delusion we need to know the concentration the polarity of the original solution. The original solution was prepared by taking .021 mg of ibuprofen and dissolving it in one mil leader. So to calculate the concentration, we need to take the moles of ibuprofen, which can be calculated by taking the milligrams divided by 1000 to get grams and then divided by the molar mass to get moles and dividing the moles of ibuprofen by the leaders of the solution. One mil leader can be calculated, Can be converted into a leader by dividing by 1000. We then get a polarity of 1.018 times 10 to the negative for Mueller Than to carry out the dilution. We have a 1.018 times 10 to the negative for Mueller solution and one mil leader of it. We want to prepare 375 times 10 to the negative six molar solution. And so we need to figure out what the new total volume will be Rearranging. This equation gives us a total volume of 27.15 million l but we already have one mil leader of solution. So we need to add to that The 27.15 -1 or the 26.15 ml. The answer then of the choices available would be 26.2 ml

answer:

Egg cells all contain an X chromosome, while sperm cells contain an X or Y chromosome.

Explanation:

This arrangement means that it is the male that determines the sex of the offspring when fertilization occurs.
