Answer:
calcium chloride dihydrate
<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
Answer:
sharing of electron
Explanation:
As seen in carbon. carbon has four electrons in his outermost shell and needs for electron by sharing of electrons it can gain it by another carbon
