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.

A sample of monochloro pentaborane (9), b5h8cl, has a mass of 20.1 g. what amount, in moles, does this mass represent?
dolphi86 [110]

The number of moles in monochloro pentaborane (9) B_5H_8Cl is 0.37056.

We know that ,

Number of moles =   Given mass/ Molar mass

Given mass of monochloro pentaborane (9) is 20.1 g

The molar mass of monochloro pentaborane (9) is

                                        =  5*B +  8*H + Cl

                                        =  5* 10.811 + 8 * 1 + 35.453

                                        = 54.241

Thus number of moles =  20.1/54.241

                                      = 0.37056
