If the pressure of a gas is 2.42 atm, what is its pressure in kPa?

Chemistry

KPa = atm x 101.325
kPa = 2.42 x 101.325
kPa = 245

Answer is: 245 kPa.

1 atm = 101.325 kPa.

p = 2.42 atm; the pressure of the gas.

p = 2.42 atm · 101.325 kPa/atm.

p = 245.20 kPa.

Atmospheric pressure (atm) is the force per unit area by the weight of air above that point.

Kilopascal (kPa) is a metric system pressure unit and equals to 1000 force of newton per square meter.

Salt dissolved in water is a solution, therefore _____.
saveliy_v [14]

Answer: Correct options are as follows.

  • salt is not chemically bonded to water.
  • salt and water retain their own chemical properties.

Explanation:

When salt is dissolved in water then it means that it is a physical change as salt has completely dissociated into ions but they are not chemically combined to the water molecules.

As a result, both salt and water will retain their chemical properties.

For example, NaCl when dissolved in water will dissociate as follows.

           NaCl \rightarrow Na^{+} + Cl^{-}

Only the particles of salt have evenly distributed in water.

And, when a components of a salt chemically combine with another substance then it will form a new compound.

Therefore, we can conclude that salt dissolved in water is a solution, therefore:

  • salt is not chemically bonded to water.
  • salt and water retain their own chemical properties.

Suppose you have an Avogadro's number of nitrogen atoms. How many grams does this represent? Enter your answer to one decimal pl
shusha [124]

Answer:

2.3 x 10-23 g.

Explanation:

The mass of a single atom is the mass number, 14, is the mass in grams of one mole of carbon.

One mole of Nitrogen atom is 6.022 x 1023 atoms (Avogadro's number). This can then used to convert a nitogen atom to grams by the ratio:

mass of 1 atom / 1 atom = mass of a mole of atoms / 6.022 x 10^23 atoms.

mass of 1 atom = mass of a mole of atoms / 6.022 x 1023

mass of 1 N atom = 14 / 6.022 x 10^23 N atoms

mass of 1 N atom = 2.325 x 10^-23 g

The mass of a single Nitrogen atom is 2.325 x 10-23 g.
