Explanation:
Hello!
In this case, as we know the mass of the total sample, we can first compute the mass of oxygen:
Next, we compute the moles of each element:
Now, we divide the moles by 0.184 moles, the fewest ones, to obtain:
Therefore, the empirical formula is:

<span>Given that a one mol solution of lithium chloride has 0.0900 mol of lithium chloride dissolved in it. Which implies that 0.910 mol of water has dissolved 0.0900 mol of Lithium chloride. which implies 0.910*18g of water has 0.0900mol LiCl.
Molality is given by moles of solute divided by kg of solvent.
so 1 kg of water has (0.0900*1000)/(0.910*18) mol of LiCl.
or 5.4945 molal solution.
So molality is 5.4945</span>
Answer:
<u>Scientists estimate that the human genome, for example, has about 20,000 to 25,000 protein-coding genes. ... In fact, compared to almost any other organism, humans' 25,000 protein-coding genes do not seem like many. The fruit fly Drosophila melanogaster, for example, has an estimated 13,000 protein-coding genes.</u>
