Calculate the number of formula units of KMnO4 in 100 mols

100 moles of KMnO₄ contain 602.2 × 10²³ formula units.

Explanation:

Given data:

Number of moles of KMnO₄ = 100 mol

Number of formula units = ?

Solution:

The given problem will be solved through Avogadro number.

1 mole contain = 6.022 × 10²³ formula units

100 mol  × 6.022 × 10²³ formula units / 1 mol

602.2 × 10²³ formula units

Thus, 100 moles of KMnO₄ contain 602.2 × 10²³ formula units.

1. 1 mole of anything contains 6.022x10^23 pieces  

d  

2. a  

3. c, number  

5. 1.24x10^24atoms / 6.022x10^23atoms/mole = 2moles h2 atoms  

6. fe2br3 mass = 2moles x mass fe + 3 moles x mass br  

molar mass = grams / number of moles = g/mole  

to find moles = g / molar mass  

to find mass = g = molar mass / moles

in the analysis of systems that involve fluid flow, we frequently encounter the combination of properties u and pv.
