You used 300 grams of Na2CO3 to wash one load of laundry. How many moles of laundry detergent did you use?
Bas_tet [7]

Answer: The number of moles of laundry detergent used is, 2.83 moles.

Explanation : Given,

Mass of Na_2CO_3 = 300 g

Molar mass of Na_2CO_3 = 106 g/mol

Formula used :

\text{Moles of }Na_2CO_3=\frac{\text{Given mass }Na_2CO_3}{\text{Molar mass }Na_2CO_3}

Now put all the given values in this formula, we get:

\text{Moles of }Na_2CO_3=\frac{300g}{106g/mol}

\text{Moles of }Na_2CO_3=2.83mol

Therefore, the number of moles of laundry detergent used is, 2.83 moles.
