First convert the kg to g ----- 0.03kg = 30g
Then divide the mass by the volume ----- 30g ÷ 25mL = 1.2
The density is 1.2g/mL<span />

From the information obtained by the problem-solving process, around 11 percentage of the school students need to have special diets.Hence, Option (C) i.e, 11 % is corrrect
<h3>What is problem-solving?</h3>
Identification of problems and marking out the steps and methods to solve them is regarded as problem-solving.
Problems can be identified only after attainment of information.
To be able to solve the problems of students suffering from a balanced diet, one out of every ten students need to include special diets in regular course.
Hence, option C holds true of the problem-solving process.
Therefore, Option (C) i.e, 11 % is corrrect
