Vera_Pavlovna [14]

Answer:

Weight of solution produced = 5135 kg

Amount of water removed = 4865 kg

Explanation:

For the balance of mass, the incoming mass of sugar must be equal to the outgoing mass. So, the incoming mass (mi) is 38% of 10000 kg

mi = 0.38x10000 = 3800 kg

The outgoing mass (mo) must be 3800 kg, and it is 74% of the total mass (mt)

mo = 0.74xmt

0.74xmt = 3800

mt = 3800/0.74

mt = 5135 kg

This is the mass of solution produced.

The amount of water removed (wr) is the amount of water incoming (wi) less the amount of water outgoing (wo). Both will be the total mass less the mass of sugar :

wi = 10000 - 3800 = 6200 kg

wo = 5135 - 3800 = 1335 kg

wr = wi - wo

wr = 6200 - 1335

wr = 4865 kg

What is the molality of a solution containing 5.0 moles of solute in 3.2 kg of solvent? Round to the nearest tenth. Don't forget
Alisiya [41]
The molality of the solution is a measure of its concentration that can be calculated by dividing the amount of substance in moles by the amount of the solvent in kilograms. Mathematically, this can be expressed as that of the equation below.
                              molality = amount of solute (mole) / amount of solvent (kg)
                              molality = 5 moles / 3.2 kg
                              molality = 1.5625 m
Rounding off the answer to the nearest tenths, will give the final answer of <em>1.6 m</em>.
