Answer:
18.73× 10²³ formula units
Explanation:
Given data:
Number of moles of Ca(NO₃)₂ = 3.11 mol
Number of formula units = ?
Solution:
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"
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
Number of formula units of Ca(NO₃)₂:
1 mole contain 6.022 × 10²³ formula units
3.11 mol × 6.022 × 10²³ formula units / 1 mol
18.73× 10²³ formula units
Answer:
Trail Mix
Explanation:
