5. When. 0.333g of a particular molecular compound dissolves in 33.3 grams of benzene, the freezing point was observed to drop b

y 0.485 °C. (In actual practice this is absurdly precise for a temperature measurement, but it makes the problem easier to solve.) What is the molecular weight of the molecular compound?

The molecular weight of the molecular compound is

x= 105.57 g/mol

<h3>What is the molecular weight of the molecular compound?</h3>

Generally,a  the equation for Mole of molecular compound is  mathematically given as

Mm= mass / molar mass

Therefore

Mm= 0.333 g / x

the equation for Morality

M = mole of solute / mass of solvent

M = \frac{(0.333 g / x )}{33.3 g / 1000 }

M= 10 / x

the equation for change in temp dt

dt= K* morality

Therefore

0.485 = \frac{5.12}{ * 10/ x}

x = (5.12 *10) / 0.485

x = 105.57 g/mol

In conclusion, molecular mass of molecular compound

x= 105.57 g/mol

An animal cell has a 0.9% saline environment is placed into a solution that is 9% saline. What will happen to the cell
Softa [21]

The concentration of cell is less than that of the solution .

Hence the cell will be called as hypotonic and the solution will be called as hypertonic.

in order to balance the concentration on the two sides of cell (inside and outside in the solution) there will be movement of solvent particles (through semipermeable membrane ) from cell (lower concentration of solute) to solution (higher concentration of solute).

Thus cell will shrink.
