Explanation:
quizizz
4.00 moles of sodium has a mass of 91.96 grams.
To find an element's molar mass, you can use its atomic weight.
Molarity is calculated by using following formula,
Molarity = Moles / Volume
Data Given:
Moles = 23 moles
Volume = 100 ml ÷ 1000 = 0.1 L
Putting values in eq. 1,
Molarity = 23 mol / 0.1 L
Molarity = 230 mol/dm³
Result:
When 23 mol of solute is dissolved in a solvent to make a solution of 100 ml, then it will have a Molarity of 230 mol/dm³.
