The amount of solid in grams required to produce 250ml of a 1 in 10 solution is 12.5 g
<h3>Preparation of solutions</h3>
Solutions are prepared when substances known as solutes are dissolved in another substance known as solvent.
In preparing solutions, the amount of solute required, concentration and volume of solution to be prepared is necessary.
- Amount is the quantity of solute in grams or moles needed to be dissolved in a given solvent in order to prepare a solution of known concentration.
- Amount in moles = mass/molar mass of solute
- Concentration of a solution is the amount of solute per volume of solution
- The volume of solution is measured in litres of millilitres
For example, to prepare a 250 mL of a 1 in 10 solution.
A 1 in 10 parts solution consists of 1 part stock solution and 9 parts solvent.
Concentration of the solution = 10%
% weight/volume = weight of solute/volume of mL * 100
Let the weight of solute = x
5% = x/250 * 100
x = 5 * 250/100
x = 12.5 g
Therefore, amount of solid in grams required to produce 250ml of a 1 in 10 solution is 12.5 g

Respiratory syncytial virus (RSV) is an important cause of disease in older adults.
Safety and immunogenicity of a stabilized RSV prefusion F subunit (RSVpreF) vaccine candidate with/without adjuvant in adults 65 - 85 years.
<h3>What are the results of Study of a Respiratory Syncytial Virus ?</h3>
All RSVpreF vaccine candidates elicited robust and persistent serum neutralizing responses when administered alone or with SIIV.
- There was no notable difference in neutralizing response between the formulations, including those containing CpG. In the Month 0,2 Cohort, there was no booster effect of dose 2.
- SIIV responses were similar or slightly lower with concomitant administration of RSVpreF. Most systemic and local reactions were mild and more frequent after RSVpreF than placebo.

Hmmmmm Ig it’s d but I’m not sure tho
Answer: Ovaries
Explanation:
Female gonads are the reproductive organs in female. These are the ovaries. Their are two ovaries in a human female which produces and stores numerous ovules or egg cells within them. The egg is released at the time of fertilization in the fallopian tube reaches upto the uterus. At the uterus the fertilization process takes place in which the sperm from male partner fuses with the egg of the female. This process results in formation of zygote which is a precursor of new life.
