Answer:
The periodic table
Explanation:
The periodic table can show the atomic number and atomic mass of any atoms easily. To convert grams of water to moles of water, you need to know the atoms that made up water molecules then find out their molecular mass. Water is made of two hydrogens and one oxygen atoms. Then you can find the atomic mass of hydrogens is 1 while oxygen is 16. The molecular mass of water will be 2*1 + 16= 18g/mol.
The best answer among the following choices would be A) since the other options are NOT nonrenewable energy sources.
I can help. What is wrong.
Answer:
the reaction was that it turned green. because it used to be brown but because the rain and carbon dioxide affected it.
Answer:
- 0.0062AU
- 0.00082.
- 106.7% error
Explanation:
a.) Average or mean value of readings, = (0.0044 + 0.0079 + 0.0062) / 3
= = 0.0062 AU
b.) The accuracy of the readings is determined by taking determining the standard deviation (SD) of the readings:
SD = ∑ /n
= 0.0000032
= 0.00000289
= 0
SD = = 0.00082.
c.) The % accuracy is the distance between the average value and true value
= = 106.7% error.
