1) Silicon dioxide formula: SiO2 ....... 2 is a subscript for the O atom
2) From the formula you have 1 molecula of SiO2 contains 1 atom of SiO2
3) Then, 0.100 mol of SiO2 contains 0.1 mol of Si
4) Multiply by Avogadro's number: 0.100mol * 6.022*10^23 atoms/mol= 6.02*10^22 atoms
Answer: 6.02*10^22 atoms
759 mililitera is equal to 0.75 liter
Physical properties include: appearance, texture, color, boiling point, melting point, ect.
It is important for scientists and engineers to be able to control the design of the material because<u> it create solutions to problems</u>.
<h3>Why material science and engineering is important?</h3>
What things are made of and why they behave the way they do are lessons we learn from materials science. Materials engineering teaches us how to use knowledge to improve things and the way they are made. Research and industry innovation in fields as diverse as aerospace and medicine are driven by materials science and engineering.
<h3>Why is it important for scientists to use the scientific method?</h3>
The scientific method is essential because: It follows a set of rules. Scientists conduct experiments in a standardized manner because the steps used in the scientific method are systematic. This suggests that their research might be spread widely.

<span>The phase of a water at a temperature of
100 degrees Celsius and 200 atmospheres is a liquid. This is confirmed by looking at a phase diagram where it shows the phase of a certain
substance at a specific temperature and pressure.</span>
