Calculate the molality of a solution formed by adding 4.40 g nh4cl to 11.0 g of water.

[NaCl] = 6.84 m

Explanation:

Molality is mol of solute / 1 kg of solvent

Let's convert the mass of solvent to kg

11 g = 0.011 kg

Now, let's convert the mass of solute to moles

Mass / molar mass

4.4 g / 58.45 g/mol = 0.0752 moles

Molality → 0.0752 mol / 0.011 kg = 6.84 m

the old alchemists made significant contributions to science even though there starting premises were off a bit. their conclusions after failure would steer them into better directions for investigation. science is no more than close observation and the initial mistakes result in rethinking and retrying experiments.
