A student added 1.28 g of sodium carbonate monohydrate and 1.28 g of calcium chloride separately into two clean, pre-weighed beakers . Then added about 10 mL of distilled water to the calcium chloride, and 20 mL to the sodium carbonate monohydrate and stirred each sample until dissolved. Slowly, with stirring, the student added small portions of the Na2CO3 solution to the CaCl2 solution. The mixture began to froth. The students stirred the mixture vigorously until it was no longer frothy, and settled to the bottom. The precipitate was filtrated, washed, and dried. The mass of the dried precipitate was 0.75 g. What is the percent yield of this reaction? Keep the correct number of significant figures.
