What is the molality of a solution that is obtained by dissolving 2.922 g of nacl into 1000.0 g of water if the molar mass of nacl is 58.44 g/mol? use molality=moles of solute/kilograms of solvent

0.05 m

Explanation:

Molality of a solution is defined as the number of moles of solute dissolved per kg of the solvent.

where,

n = moles of solute

To calculate the moles, we use the equation:

= weight of solvent in g=1000 g

Molality =

Thus molality of the solution is 0.05m

lysosome is this part of the cell is surrounded by a very thick outer membrane to protect the rest of the cell from its strong enzymes.

the cladogram shown here shows similarities and differences among several classes of vertebrates. anatomically, the four have limb structure as their common ancestor. we might separate the mammals from the other three classes because they a) divergent; do not lay eggs b) identical; are warm-blooded c) varied; a four chambered heart d) homologous; have mammary glands
