Answer:
The Median is 5
Step-by-step explanation:
The median is the middle number in a set of data, when the data has been written in size order.
0 1 2 4 <u>5 5</u> 5 6 6 6
As there is an even number of data the median is the average of the middle two values. As the middle 2 values are both 5, then the average of these is also 5. Therefore, the median is 5.
To find the mean of the set of data, add all the values together then divide by the number of data values:
(0 + 1 + 2 + 4 + 5 + 5 + 5 + 6 + 6 + 6) ÷ 10 = 4
Therefore, the mean is 4.
The Median is a better measure of central tendency as extreme values (outliers) do not affect it. From inspection of the dot plot, the majority of the data values are 5 and 6. Therefore, the lower values *could* be outliers, so 5 is a more realistic measure of central tendency.

Answer:
513 g of C₁₂H₂₂O₁₁ will contain 18 moles of Carbon atoms.
Step-by-step explanation:
English Translation
You would know how to say the number of moles of carbon atoms in 513 g of C₁₂H₂₂O₁₁ (Molar mass of C₁₂H₂₂O₁₁: 342 g.
Solution
From the molecular formula for the compound,
1 mole of C₁₂H₂₂O₁₁ consists of 12 moles of carbon atoms.
We just need to find the number of molesnof the mass of C₁₂H₂₂O₁₁ provided.
Number of moles = (mass)/(molar mass)
Mass of C₁₂H₂₂O₁₁ = 513 g
Molar mass of C₁₂H₂₂O₁₁ = 342 g
Number of moles of C₁₂H₂₂O₁₁ present
= (513/342) = 1.5 moles
1 mole of C₁₂H₂₂O₁₁ consists of 12 moles of carbon atoms.
1.5 moles of C₁₂H₂₂O₁₁ will contain (1.5×12/1) moles of carbon atoms, that is, 18 moles of Carbon atoms.
Hope this Helps!!!
