A 150. 0 ml sample of an aqueous solution at 25°c contains 15. 2 mg of an unknown nonelectrolyte compound. If the solution has an osmotic pressure of 8. 44 torr, what is the molar mass of the unknown compound?.

Answers

Answer:

3.141592653589793238

Explanation:

3.141592653589793238

The molar mass of the unknown compound in the aqueous solution was 223.2 g/mol.

What is osmotic pressure?

Osmotic pressure can be described as the minimum pressure requires to be applied to a solution to stop the flow of its pure solvent across a semipermeable membrane. The measurement of the tendency of a solution to take in a pure solvent by osmosis is osmotic pressure.

To determine the molar mass of a compound from the given weight, the concentration of the compound needs to be determined.

π = i ×MRT

8.44 = 1×M× 62.36 ×298

M = 4.54 × 10⁻⁴ M

Given the mass of the unknown compound = 15.2 mg = 0.0152 g

The volume of the compound = 150 ml =0.150 L

From the molarity of the compound, we can determine the molar mass as:

Molarity = mass/(Molar mass × Volume)

Molar mass =  mass/(Molarity × Volume)

Molar mass = 0.0152/ (4.54 × 10⁻⁴ × 0.150)

Molar mass = 223.2 g/mol

(a.) a 0.7549g sample of the compound burns in o2(g) to produce 1.9061g of co2(g) and 0.3370g of h2o(g).

Answers

The individual mass of C, H and O in given sample are 0.5196 g, 0.0374 g and 0.1979 g respectively.

Moles of CO2 formed can be calculated as

= Mass of CO2 / Molar mass of CO2

= 1.9061 / 44 = 0.0433 moles

Calculation of no. of moles of carbon

Now, moles of C which is present in one mole of CO2 = 1 mole

Moles of C in 0.0433 moles of CO2 = 0.0433 moles

As we know that, molar mass of C = 12 g / mol

Mass of C in 0.7549 g of given sample can be calculated as

= 0.0433 × 12 =0.5196 g

Mass of H2O formed = 0.3370 g

Similarly, Molar Mass of H2O = 18 g / mol

Moles of H2O = 0.3370 / 18 = 0.0187 moles

Moles of H present in 1 mole of H2O = 2 moles

Moles of H present in 0.0187 mole of H2O = 2 × 0.0187 = 0.0374 moles

Molar mass of H = 1 g / mol

Mass of H contained in 0.7549 g of sample = 1 × 0.0374= 0.0374 g

Mass of O in 0.7549 g sample can be calculated as

= 0.7549 – [(Mass of C ) + (Mass of H) ]

= 0.7549 – [ (0.5196) + (0.0374) ]

= 0.1979 g

Thus, we calculated that the individual mass of C, H and O in given sample are 0.5196 g, 0.0374 g and 0.1979 g respectively.

If a meteorologist says that the air pressure is getting lower, what
would you expect to see happen to Torricelli's mercury barometer?

Answers

If the air pressure is reduced, the pointer or hand of the Torricelli's mercury barometer sinks or falls to the bottom.

An inverted (upside-down) glass tube standing in a mercury bath is a Torricellian barometer, also known as a mercury barometer. Some of the mercury's surface particles climb up the tube as a result of air pressure pushing down on it. The mercury rises more rapidly when air pressure increases.

A tall closed tube placed upside-down in a mercury bath, which is a thick liquid metal at room temperature, creates the simplest type of barometer, with the liquid rising partially up the tube as it does in a thermometer. Because mercury is more practical than water for barometers, we utilize it instead. Due to its lower density than mercury, water will be lifted by air pressure significantly higher up a tube than the same volume of mercury.

what happen when chemical reaction takes place between an acid and base​

Answers

Answer:

When an acid reacts with a base, they undergo neutralization and their opposite pH levels cancel each other out. This happens through the double displacement of ions or, put simply, the ions switch partners.

Explanation:

When an acid and a base are placed together, they react to neutralize the acid and base properties, producing a salt. The H(+) cation of the acid combines with the OH(-) anion of the base to form water. The compound formed by the cation of the base and the anion of the acid is called a salt.

An example of neutralization reaction is: HCL + NaOH ⇆ NaCl +

acid + base ⟶ water + salt.

HCl(aq) + KOH(aq) ⟶ H 2O(ℓ) + KCl(aq)
