Answer:
The mean is 
The 90% confidence interval is:
![i_{0.90}=[0.492\frac{mg}{L},0.514\frac{mg}{L}]](https://tex.z-dn.net/?f=i_%7B0.90%7D%3D%5B0.492%5Cfrac%7Bmg%7D%7BL%7D%2C0.514%5Cfrac%7Bmg%7D%7BL%7D%5D)
Explanation:
1. First organize the data:





As there are 5 data, the sample size (n) is n=5
2. Calculate the mean x:
The mean is calculated adding up all the data and divide them between the sample size.


3. Find 90% confidence interval.
The formula to find the confidence interval is:
(Eq.1)
where x is the mean, d is the standard deviation and n is the sample size.
And




4. Find the standard deviation





5. Replace values in (Eq.1):
![i_{0.90}=[0.503+/-1.645*(\frac{0.015}{2.236})]](https://tex.z-dn.net/?f=i_%7B0.90%7D%3D%5B0.503%2B%2F-1.645%2A%28%5Cfrac%7B0.015%7D%7B2.236%7D%29%5D)
For the addition:
![i_{0.90}=[0.503+1.645*(\frac{0.015}{2.236})]](https://tex.z-dn.net/?f=i_%7B0.90%7D%3D%5B0.503%2B1.645%2A%28%5Cfrac%7B0.015%7D%7B2.236%7D%29%5D)

For the subtraction:
![i_{0.90}=[0.503-1.645*(\frac{0.015}{2.236})]](https://tex.z-dn.net/?f=i_%7B0.90%7D%3D%5B0.503-1.645%2A%28%5Cfrac%7B0.015%7D%7B2.236%7D%29%5D)

The 90% confidence interval is:
![i_{0.90}=[0.492,0.514]](https://tex.z-dn.net/?f=i_%7B0.90%7D%3D%5B0.492%2C0.514%5D)
Answer:
B. A chemical formula that shows the relative number of each type of
atom in a molecule, using the smallest possible ratio
Explanation:
The empirical formula of a compound shows the relative number of each type of atom in a molecule and it uses the smallest possible ratio.
- It expresses the composition of the compound in the simplest whole number ratio of the atoms of the different elements that makes up the compound.
- To determine empirical formula of a compound , two pieces of information are needed;
- A. mass of each element in the compound
- B. Relative atomic mass of the constituent elements.
