Anna11 [10]3 years ago
4 0

Answer:

V = 53.82 L

Explanation:

Given data:

Mass of benzene = 45 g

Temperature = 100°C (100+273 = 373 K)

Pressure = 250 torr (250/760 = 0.33 atm)

Volume of benzene = ?

Solution:

Number of moles of benzene:

Number of moles = mass /molar mass

Number of moles = 45 g/ 78.11 g/mol

Number of moles = 0.58 mol

Volume of benzene:

PV = nRT

V = nRT/P

V = 0.58 mol × 0.0821 atm.L/mol.K × 373 k / 0.33 atm

V = 17.76 atm.L /0.33 atm

V = 53.82 L

Define the law of conservation of charge and provide an example.
iren2701 [21]

Answer:

Conservation of Charge is the principle that the total electric charge in an isolated system never changes. The net quantity of electric charge, the amount of positive charge minus the amount of negative charge in the universe, is always conserved.

Use the value of the Avogadro constant (6.02 × 1023 mol–1) to calculate the total number of atoms in 7.10 g of chlorine atoms. (
kolbaska11 [484]

The total number of atoms in 7.10g of chlorine is 1.204 × 10²³atoms.

HOW TO CALCULATE NUMBER OF ATOMS:

  • The number of atoms in a substance can be calculated by multiplying the number of moles in that substance by Avogadro's number as follows:

  • no. of atoms = no. of moles × 6.02 × 10²³ mol-¹

  • The number of moles in 7.10g of Cl is calculated as follows:

no. of moles = mass ÷ molar mass

no. of moles = 7.10g ÷ 35.5g/mol

no. of moles = 0.2mol

no of atoms = 0.2mol × 6.02 × 10²³

no. of atoms = 1.204 × 10²³atoms.

  • Therefore, the total number of atoms in 7.10g of chlorine is 1.204 × 10²³atoms.
