Matter and Measurement

In the universe, there is matter, energy, and void space. The universe contains energy and void space. The definition of matter can be considered as something which possesses mass and consumes space. Chemistry is that branch of science which deals with the study of matter. Under chemistry, nature, composition, and the changes occurring to matter are discussed.

Question

100%

I have a question.
for the first question, wouldn't I divide 2.202 by 6.626 and divide by 100?? & how would I work the second questions?

Expert Solution

Step 1

Mass percent = (mass of solute / mass of solution) x 100

(1) mass percent of silicon dioxide =( mass of silicon dioxide/ mass of whole sample) x 100

(2) mass of silicon dioxide = (mass percent of silicon dioxide x mass of sample)/ 100
