Answer:
7.54%
Explanation:
A hydrate is a salt that has molecules of water incorporated into the crystals. It is represented by the molecular formula of the salt followed by how many molecules of water it has: XY.nH₂O.
So, the mass of water in the sample will be the difference between the hydrate and the salt without water:
mass of water = 1.034 - 0.956 = 0.078 g
The mass percentage is the mass of water divided by the total mass, and then multiplied by 100%:
(0.078/1.034)x100%
7.54%
Volume would be 6.79792764 cm³. Just divide 131.2 by 19.3
ρ=Mass/Volume
Volume= mass/density
Answer:
The biggest known human gene, is made up of about 2.4 million bases. The Human Genome Project also gave us more detailed information about chromosomes. It turns out that chromosome 1 contains the most genes, while the Y chromosome has the fewest.

The series which is in order of increasing boiling point is CH3CH2CH3 CH3COCH3 CH2CH2CH3OH
However, the boiling point of an organic substance is the temperature at which the vapor pressure of the liquid organic substance equals the pressure surrounding the liquid and the liquid changes into a vapor.
<h3>What are organic compounds?</h3>
Organic compounds are substance containing carbon and hydrogen. Some few organic compounds include:
- Alkanes
- Alkenes
- Alkynes
- Alkanols
- Alkanals
- Alkanones
- Esters
- Amines
So therefore, the series which is in order of increasing boiling point is CH3CH2CH3 CH3COCH3 CH2CH2CH3OH
