b. Pressure

Explanation:

Pressure is a physical effect that can change the boiling point of a substance.

Pressure is the force per unit area on a body.

  • A substance will boil when the vapor pressure of its heated molecules is greater than the atmospheric pressure.
  • The higher the atmospheric pressure, the higher the temperature and energy required to boil  a substance.
  • At high altitude, the atmospheric pressure is low and the boiling point of substances is lower.

How many li are in 2.5 moles of li​
NARA [144]

Answer:

15.06 × 10²³ atoms of Li

Explanation:

Given data:

Number of moles of Li = 2.5 mol

Number of toms of Li = ?

Solution:

The given problem will solve by using 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.

The number 6.022 × 10²³ is called Avogadro number.

For example,

18 g of water = 1 mole = 6.022 × 10²³ molecules of water

1.008 g of hydrogen = 1 mole = 6.022 × 10²³ atoms of hydrogen

For 2.5 mol of Li:

1 mole of lithium = 6.022 × 10²³ atoms of Li

2.5 mol × 6.022 × 10²³ atoms of Li / 1 mol

15.06 × 10²³ atoms of Li
