Apply the ideal gas law to solve problems

Chemistry
1 answer:
Rus_ich [418]3 years ago
6 0

Answer:

Volume of gas ( V ) = 19.8935 L

Explanation:

Data Given:

no. of mole of gas (n) = 21.0 mole

Pressure P = 78.0 atm

Temperature T = 900 K

Ideal gas constant = 0.08206  L atm K⁻¹ mol⁻¹

Volume of gas = ?

Formula used for Ideal gases

                                               <em> </em><em> </em>PV = nRT

As we have to find volume of the gas:

We will rearrange the ideal gas equation as below:

                                         V = nRT / P  ........................................... (1)

Put value in equation (1)

                  V =  21.0 mol x 0.08206  L atm K⁻¹ mol⁻¹ x 900K / 78.0 atm

                  V = 19.8935 L

Volume of gas V = 19.8935 L

How many moles are in 4.3 x 10 ^22 molecules of Na3PO4
Sever21 [200]

Answer:

0.071 moles of Na₃PO₄ .

Explanation:

Given data:

Number of molecules of Na₃PO₄ = 4.3× 10²² molecules

Number of moles = ?

Solution:

1 mole contain 6.022 × 10²³ molecules

4.3× 10²² molecules × 1 mol / 6.022 × 10²³ molecules

0.71× 10⁻¹ mol

0.071 mol

The number 6.022 × 10²³ is called Avogadro number.

"It is the number of atoms , ions and molecules in one gram atom of element, one gram molecules of compound and one gram ions of a substance"

-Dominant- [34]

Answer:

It makes the pasta to get hot faster and boil quicker.

Explanation:

Adding salt to water actually raises the boiling point of the water, due to a phenomenon called boiling point elevation. Essentially, adding any non-volatile solute such as salt to a liquid causes a decrease in the liquid’s vapour pressure. A liquid boils when the vapour pressure above it equals atmospheric pressure, so a lower vapour pressure means you need a higher temperature to boil the water. The reason salt makes water boil faster has to do with specific heat capacities, or the energy it takes to raise the temperature of a substance. Salt ions dissolved in water bind to water molecules, holding them stable and making it harder for them to move around. As a result, the non-salt bound water molecules receive more of the energy provided by the stove, and therefore they get hot faster and boil quicker.
