Final answer:
The mass percent of sodium carbonate in a mixture can be calculated by dividing the mass of sodium carbonate in the mixture by the total mass of the mixture, and then multiplying by 100.
Step-by-step explanation:
The mass percent of sodium carbonate in a mixture can be calculated by dividing the mass of sodium carbonate in the mixture by the total mass of the mixture, and then multiplying by 100.
For example, let's say we have a mixture that contains 10 grams of sodium carbonate and 100 grams of water. The mass percent of sodium carbonate in this mixture would be (10 grams / 110 grams) * 100 = 9.09%.
So, the mass percent of sodium carbonate in a mixture depends on the amount of sodium carbonate and the total mass of the mixture.
