The peaks are there where the centre of the concentric circles lie. (Not circles exactly)

You can count a total 4 of them.

So there are a total of 4 peaks

See the attachment. I have marked them with a cross.

WITCHER [35]

Answer:

<h3>If the substance has high melting/boiling point, if it requires high temperature to dissociate into simpler particles, if it's structure is hard and if it conducts heat and electricity quite frequently, then it would be "Ionic compound" otherwise, it will be covalent compound.</h3>

What is the molality of a solution made by dissolving 50.00 g of glucose, C6H12O6, in 500.0 g water. Give your answer to 3 signi
hichkok12 [17]

Answer:

m = 0.5556 mol/kg

Explanation:

The molality of any solution is calculated using the following expression:

m = moles solute / kg solvent (1)

So in order to calculate the molality of this solution, we need to calculate the moles of the glucose using the expression:

n = mass / molecular weight  (2)

The molecular weight of glucose, can be calculated using the molecular mass of the atoms in the glucose:

C = 12 g/mol; H = 1 g/mol; O = 16 g/mol

the molecular weight is:

MW = (12*6) + (12*1) + (6*16) = 180 g/mol

Then, the moles of glucose:

moles = 50 / 180 = 0.2778 moles

The solvent in this case is water, and 500 g of water is 0.5 kg of water, so the molality is:

m = 0.2778 / 0.5

m = 0.5556 mol/kg
