In step 2 of the experimental procedure, you added 6 M sodium hydroxide to the copper(II) nitrate solut form copper(II) hydroxid
kicyunya [14]

Answer:

The solution becomes colorless and a light blue precipitate is formed.

Explanation:

When sodium hydroxide is added to copper(II) nitrate solution, a precipitate of  copper(II) hydroxide is formed.

The solution gradually becomes colorless as the light blue precipitate appears.

The reaction is complete (enough sodium hydroxide has been added) when the blue color of the solution completely disappears.

The equation of the reaction is;

Cu(NO3)2(aq) + 2NaOH(aq) → Cu(OH)2(s) + 2NaNO3(aq)

Menthol is a crystalline substance with a peppermint taste and odor. When 1.48 g of menthol is dissolved in 25.0 g of cyclohexan
pishuonlain [190]

Answer:

Molar mass of menthol is 155.86 g/mol

Explanation:

Let's apply the colligative property of freezing point depression:

ΔT = Kf . m . i

As menthol is an organic compound we assume the i (Van't Hoff factor as non electrolytic, so i = 1)

m = mol /kg (molality)

Kf = Cryoscopic constant, in this case, for cyclohexane

ΔT = T° freezing of pure solvent - T° freezing solution

7.90°C = 20.8°C / m . m . 1

7.90°C / 20.8 m/°C = m

0.380 m = molality

0.380 moles are the moles of solute (menthol) dissolved in 1kg of solvent, but our mass of solvent is 25 g.

Let's convert the g of solvent to kg to work with molality

25 g = 0.025 kg

molal . solvent mass = moles of solute

0.380 mol /kg . 0.025kg = 9.49×10⁻³ moles

Now, we have the moles and the mass of solute. Let's determine the molar mass of menthol (grams / moles)

1.48 g / 9.49×10⁻³ m = 155.86 g/m

A rock displaces 475ml of water what’s its volume
grin007 [14]

Answer:

The rock displaces 475 mL of water.

475 mL is the volume of the rock.

1 mL = 1 cm^3  

The mass is just density times volume.

m = 475 * 2.5 = 125 g
