Multiply .800 moles of O2 by Avagadro's number divided by 1 mole. This will get rid of the moles on the bottom and leave you with molecules. So technically .800 times 6.02x10^23.
Answer:0.5 m/s
Explanation: Divide D: distance To L: line 3.5 divided by 1.75 gives you 0.5 m/s
distance/time

Answer:
0.087 moles of water
Explanation:
Given data:
Number of molecules of water = 5.24×10²² molecules
Number of moles of water = ?
Solution:
Avogadro number:
It is the number of atoms , ions and molecules in one gram atom of element, one gram molecules of compound and one gram ions of a substance. The number 6.022 × 10²³ is called Avogadro number.
1 mole = 6.022 × 10²³ molecules of water
5.24×10²² molecules × 1 mol / 6.022 × 10²³ molecules
0.87×10⁻¹ mol
0.087 mol
The correct answer is C. A television
Explanation:
Plasma is a particular state of matter that differs from liquid, solid, and gas because plasma is a gas but contains mainly particles that have lost their electrons or ions. This makes plasma have properties other states do not have. Additionally, plasma is now widely used in technologies, including televisions, this is because plasma is used in thousands of small containers to create the images in a Tv. This leads to high quality and precise images. Therefore, the commercial technology that commonly uses plasmas is a television.
