Answer: A and D, I believe
Explanation:
Answer:
Explanation:
When a salt is dissolved , it increases the boiling point . Increase in boiling point depends upon number of ions . So it is a colligative property .
.19 m AgNO₃ . Each molecule will ionize into two ions . So effective molar concentration is 0.19 x 2 = .38 m
0.17 m CrSO4.Each molecule will ionize into two ions . So effective molar concentration is 0.17 x 2 = .34 m
0.13 m Mn(NO₃)₂. Each molecule will ionize into three ions . So effective molar concentration is 0.13 x 3 = .39 m
0.31 m Sucrose(nonelectrolyte). Molecules will not ionize . So effective molar concentration is 0.31 x 1 = .31 m
Higher the molar concentration , greater the depression in boiling point .
So lowest boiling point is 0.13 m Mn(NO₃)₂.
second highest boiling point is 0.19 m AgNO3.
Third lowest boiling point is 0.17 m CrSO4
Highest boiling point or lowest depression 0.31 m Sucrose.
a . 4
b . 1
c . 2
d . 3
<span>A-U-G - G-C-A
Met - Ala
If AUG is going to be in the beginning of the chain, </span>A-U-G, also will mean a start codon. For eukaryotes, codon for Met means start of the amino acid chain.
Answer:
127.2 g/cm^3
Explanation:
(Think of the DMV triangle. I'll attach a picture)
Volume = Density x Mass
Volume = 2.12 g/cm3 x 60.0 g
Volume = 127.2 g/cm3
Hope this helps!!!
