Suppose a student added the ethyl alcohol straight to the solution from the baggie without filtering it through the cheesecloth first. what do you think the student would observe? would the student be successful in extracting the dna? explain briefly why you think this.

I think students will be able to see fine white strands which are not soluble in ethanol.  DNA is not soluble in ethanol. The colder the ethanol, the less soluble the DNA will be in it. I think the the student would be successful in extracting the DNA. Hope this answers the question. Have a nice day.

2,909 M

Explanation:

molair mass is of.ethylene is 26,04 g/mol

first you need to calculate how much mL 3 kg is. You can do this by using the density of ethylene: 1,1 g/mL.

3000 g x 1.1 = 3300 mL = 3,3 L

Next you need to calculate the amount of moles:

250 g / 26,04 g/mol = 9,60 mol

Now you can calculate the molarity:

9,6/3.3 = 2,909 M

I don't know the answer for the second question. I'm sorry.
