## Which has more Formula Units 1 gram NaCl or 1 gram of KCl?

This is because the Potassium atom (K) is heavier than the Sodium atom (Na). Thus one gram of NaCl will contain more molecules (formula units) than one gram of KCl.

## What is the formula weight of KCl?

74.5513 g/mol

## How many moles are in 25g of KCl?

25122.4 = moles. 2.05 moles of Potassium Chlorate.

## How many moles are in 74 grams of KCl?

74g KCl = 0.99 mole of KCl (molar mass KCl= 74.6g)

## How do I calculate moles?

- First you must calculate the number of moles in this solution, by rearranging the equation. No. Moles (mol) = Molarity (M) x Volume (L) = 0.5 x 2. = 1 mol.
- For NaCl, the molar mass is 58.44 g/mol. Now we can use the rearranged equation. Mass (g) = No. Moles (mol) x Molar Mass (g/mol) = 1 x 58.44. = 58.44 g.

## What is the mass of 5.24 mole of KCl?

K = 39.1 g; Cl = 35.6 g.

## How many moles of KCl are in 74.0 grams of KCl?

The mass of a potassium atom is 39 amu and the mass of a chlorine atom is 35 amu. This means that KCl has a mass of 74 amu and one mole of KCl is 74 grams. To make a 1 M solution of KCl you would dissolve 74.0 grams in one liter of water. For 1 liter of a 3.20 M solution, we need 3.20 moles of solute.

## How much KCl in grams should the chemist use?

Step1: Molarity(M) is defined as number of moles of solute dissolved in one litre (or one cubic decimetre) of solution. = 18.64 g. Thus, the required mass of KCl is 18.64 g.

## How many grams is KClO3?

The SI base unit for amount of substance is the mole. 1 mole is equal to 1 moles KClO3, or 122.5495 grams.

## How many moles are in 2 grams of oxygen?
