Calculate the concentration of a 220 g solution of calcium chloride (CaCl2) that has a volume of 11 L

Chemistry
1 answer:

Answer: The concentration of the solution is 0.18 M

Explanation:

Molarity of a solution is defined as the number of moles of solute dissolved per liter of the solution.

Molarity=\frac{n}{V_s}

where,

n = moles of solute

V_s = volume of solution in L

moles of CaCl_2 = \frac{\text {given mass}}{\text {Molar mass}}=\frac{220g}{111g/mol}=1.98mol

Now put all the given values in the formula of molality, we get

Molarity=\frac{1.98mol}{11L}=0.18M

Therefore, the concentration of the solution is 0.18 M

For metalloids on the periodic table, how do the group number and the period number relate?
Studentka2010 [4]

Answer : The correct option is A.

Explanation :

Metalloid : Metaloids are the elements whose properties lie between the metals and non-metals.

There are six commonly elements which are boron, silicon, germanium, arsenic, antimony and tellurium. The rare elements are polonium and astatine.

The relation between the group number and period number of metalloid is that the lower the group number, the lower the period numbers and the metalloids are found in a diagonal moving down from left to right in the periodic table.
