The following carbon-based molecules store information are found in living things.
All organism are made of 4 type of carbon-based= carbon hydrate, lipids, proteins, and nuclear acid
What are the following answers?
Answer:
a. Al2S3.
Explanation:
Molar mass of Al = 26.98
Molar mass of S = 32.06.
Ratio of AL:S is 1 : 1.78
Dividing by the moles we get:
0.0371 : 0.0555
= 1 : 1.5
So its Al2S3.
11.412 x 10^23.
EXPLANATION:
5.5 oz = 155.92 g
155.92 g x (1 mol/82.2 g) = 1.8956 mol
(6.02 x 10^23) x 1.8956 = 11.412 x 10^23
