If 27.0 mL of Ca(OH)2 with an unknown concentration is neutralized by 32.40 mL of 0.185 M HCl, what is the concentration of the

zhannawk [14.2K]

Given information : Volume of HCl = 32.40 mL

$32.40 mL\times \frac{1 L}{1000 mL}$

Volume of HCl = 0.0324 L

Concentration of HCl = 0.185 M or 0.185 mol/L (M = mol/L)

Volume of Ca(OH)2 = 27.0 mL

$27.0 mL\times \frac{1 L}{1000 mL}$

Volume of Ca(OH)2 = 0.027 L

We need to find the concentration of Ca(OH)2.

To find the concentration of Ca(OH)2 we need moles and volume of Ca(OH)2.

$Concentration (Molarity) = \frac{(Moles of Ca(OH)2)}{(Volume of Ca(OH)2)}$

Moles of Ca(OH)2 can be calculated using stoichiometry and volume of Ca(OH)2 is already given to us.

Step 1 : Find the moles of HCl using its given volume and concentration.

$Moles = Concentration \times Volume in L$

$Moles = 0.185\frac{mol}{1L}\times 0.0324 L$

Moles of HCl = 0.005994 mol HCl

Step 2 : We need to find moles of Ca(OH)2 using mol of HCl with the help of mole ratio.

Mole ratio are the coefficient present in front of the compound in a balanced equation.

Mole ratio of Ca(OH)2 : HCl = 1:2 ( 1 coefficient of Ca(OH)2 and 2 coefficient of HCl)

$(0.005994 mol HCl)\times \frac{(1 mol Ca(OH)2)}{(2 mol HCl)}$

Moles of Ca(OH)2 = 0.002997 mol Ca(OH)2

Step 3 : Find the concentration of Ca(OH)2 using its moles and volume.

$Concentration (Molarity) = \frac{(Moles of Ca(OH)2)}{(Volume of Ca(OH)2)}$

Moles of Ca(OH)2 = 0.002997 mol and volume of Ca(OH)2 = 0.027 L

$Concentration (Molarity) = \frac{(0.002997 mol)}{(0.027 L)}$

Concentration of Ca(OH)2 = 0.111 mol/L or 0.111 M

Which among the following statements is FALSE? Group of answer choices None of the above A liquid has a definite volume; but it

Vesna [10]

Answer: None of the above statements is false.

Explanation:

In a solid substance, particles are closely held together due to which a solid substance has definite shape and volume. Therefore, solids are also incompressible in nature.

In liquids, the molecules are slightly away from each other due to which they can slide past each other. Hence, liquids do not have a fixed shape but they have a definite volume. Liquids are also incompressible in nature.

In gases, the particles are held by Vander waal forces due to which they move rapidly from one place to another. Hence, gases are highly compressible in nature.

Thus, we can conclude that none of the given statements are false.
