How many moles of potassium chloride are in 28 grams of KCl?

A.).265 mole KCl

B.).856 mole KCl

C.).376 mole of KCl (think it's this but idk)

D.) 1.2 mole KCl

0.3758moles

Explanation:

moles of kcl = mass of kcl / molar mass of kcl = 28/74.5 = 0.3758moles

We have 0.376 moles in 28.0 grams of KCl

Option C is correct.

Explanation:

Step 1: Data given

Mass KCl = 28.00 grams

Molar mass KCl = 74.55 g/mol

Step 2: Calculate moles KCl

Moles KCl = mass KCl / moalr mass KCl

Moles KCl = 28.0 grams / 74.55 g/mol

Moles KCl = 0.376 moles KCl

We have 0.376 moles in 28.0 grams of KCl

Option C is correct.
