Missing question:

0.0854 kilogram  

85.4 grams  

8.54 hectograms  

85,400 milligrams.

Answer is: 8.54 hectograms is not the same.

1 cg = 0.01 g; one centigram is equal to 10⁻² grams.

m = 8540 cg.

m = 8540 cg · 0.01 g/cg.

m = 85.4 g.

1) m = 0.0854 kg.

1 kg = 1000 g.

m = 0.0854 kg · 1000 g/kg.

m = 85.4 g; it is the same.

2) m = 85.4 g; it is the same.

3) m = 8.54 hg.

1 hg = 100 g; one hectogram is 100 grams.

m = 8.54 hg · 100 g/hg.

m = 854 g; it is not the same.

4) m = 85400 mg.

1 mg = 0.001 g.

m = 85400 mg · 0.001 g/mg.

m = 85.4 g; it is the same.

How much potassium chloride is needed to make 0.500 m solution with 1.50 L of water?
Andrew [12]

Answer:

55.9 g KCl.

Explanation:

Hello there!

In this case, according to the definition of molality for the 0.500-molar solution, we need to divide the moles of solute (potassium chloride) over the kilograms of solvent as shown below:

m=\frac{mol}{kilograms}

Thus, solving for the moles of solute, we obtain:

mol=m*kilograms

Since the density of water is 1 kg/L, we obtain the following moles:

mol=0.500mol/kg*1.50kg\\\\mol=0.75mol

Next, since the molar mass of KCl is 74.5513 g/mol, the mass would be:

0.75mol*\frac{74.5513g}{1mol}\\\\55.9g \ KCl

Regards!
