Another name for biomas is renewable energy
Answer:
Explanation:
carbon in group 4A needs 4 more electrons to be stable
hydrogen in group 1A has one electron needs 1 more t o be stale
oxygen in group 6A has 6 and needs 2 more to be stable
They all obtain this by sharing electrons 8 around C &O, 2 around H
H : C: H

<u>Answer:</u> The molar mass of molecule X is 162.5 g/mol
<u>Explanation:</u>
We are given:
0.9 % of NaCl
This means that 0.9 grams of NaCl is present in 100 grams of solution
5 % of molecule X
This means that 5 grams of molecule X is present in 100 grams of solution
To calculate the concentration of solute, we use the equation for osmotic pressure, which is:
Or,
where,
i = Van't hoff factor
R = Gas constant =
T = temperature of the solution
According to the question:
Osmotic pressure of both the solutions are same.
So, the equation becomes:
where,
Putting values in above equation, we get:
Hence, the molar mass of molecule X is 162.5 g/mol
