Answer:
Um did you post something I don't see nothing
Explanation:
A mirror is opaque, meaning that it reflects the light and images that shine on it's reflective surface.
Answer:
4.65 moles
Explanation:
To calculate this, we can use Avogradro's Number: 6.022*10^23
![2.8*10^2^4*\frac{1mole}{6.022*10^2^3} =4.65mol](https://tex.z-dn.net/?f=2.8%2A10%5E2%5E4%2A%5Cfrac%7B1mole%7D%7B6.022%2A10%5E2%5E3%7D%20%3D4.65mol)
So, there are 4.65 moles in 2.8*10^24 atoms of Ti
The Bohr model is the basis for chemistry

</h3>
In general, some people equate mass and weight.
Mass is one of the principal quantities, which is related to the matter , whereas weight is a force that leads to the center of the earth (Earth's gravitational force)
Steps that can be taken to find the mass :
- 1. Weigh graduated cylinder (empty)
- 2. Pour the alcohol in the beaker into the graduated cylinder to the level of 40 ml
- 3. Weigh again graduated cylinder + poured alcohol
- 4. mass of alcohol 40 ml = mass in 3rd step - mass in the first step
