Answer:
The number of chlorine atoms present in 
units of gold III chloride is 
Explanation:
Formula of Gold (III) chloride: 
<em>Avogadro Number</em> : Number of particles present in <u>one mole</u><u> </u>of a substance.
Using,
= 1 mole(0.9999 , nearly equal to 1 )
The given Gold III chloride sample is 1 mole in amount.
= 1 mole of
In this Sample,
1 mole of will give = 3 mole of Chlorine atoms
1 mole of Cl contain =
3 mole of Cl contain = 
3 mole of Cl contain =
So,
The number of chlorine atoms present in units of gold III chloride is
Answer:
C₃H₆O₃
Explanation:
Data:
EF = CH₂O
MM = 90. g/mol
Calculations:
EF Mass = (12.01 + 2.016 + 16.00) u = 30.03 u
The molecular formula is an integral multiple of the empirical formula.
MF = (EF)ₙ
MF = (CH₂O)₃ = C₃H₆O₃
The answer to the question what is true about the location of Polaris in the azimuth-altitude coordinate system, it is the letter "C" which is "Its altitude depends on the observer's altitude." For example, if the observer is in the equator, observer's altitude is zero and then the Polaris altitude is also zero.

First one, 6.250 * 10^(-4). Second one, 9.532 * 10^6. Third one, 4.38904 * 10^5. Forth one, 4.5833 * 10^(-3). The zero before first non-zero number can ignore.
