If I have 2 samples of limestone, sample 1 weighing 0.732g and sample 2 weighing 0.825g. Both were dissolve do in15ml of 3.00M of HCL. 1.5g of (NH4)2SO4 was added to each sample. Then 20ml of 2.00M NH3OH was added to each sample. How do I calculate the moles of CaCO3 in limestone AND the mass of CaCO3 in limestone ?

(Questions 1 and 2) An experiment is conducted. The sample size is 30. A sample average is observed. To test the null hypothesis that the population average equals a particular value versus the alternative hypothesis that the population average is not equal to a particular value, a two tailed hypothesis test is performed. (Critical region in the two tails). The test statistic— the sample average—is normally distributed. The stated significance levels for the test are 5% and 1%. In other...
