You complete a chemical reaction and recover 79 grams of product. However, you calculate you should have recovered 104 grams of
spin [16.1K]
Percent yield is calculated using:
percent \: yield =  \frac{actual \: yield}{theoretical \: yield}   \times 100\%

Your actual yield is how much you actually had at the end of the experiment = 79g.

Your theoretical yield is how much you calculated you should have gotten in an ideal, perfect experiment = 104g.

So put those values into the equation:
percent \: yield =  \frac{79}{104}  \times 100\% = 76\%

A sample of tap water contains 1.95 x 10^3 ppm caco3. assuming the density of the tap water is 1.00 g/ml, calculate the mass of
Pavlova-9 [17]
3.9 grams CaCO3  
The mass of 2.0 L of water with a density of 1.00 g/ml is 2000 grams.And 1 ppm of that is 2000 / 1000000 = 0.002 grams. So just multiply by the ppm of CaCO3, giving 0.002 g * 1.95x10^3 = 3.90 grams.  
Since the least accurate datum we have is 2 significant figures, the result should be rounded to 2 significant figures, giving 3.9 grams.
