Answer #1

In the two samples of calcium fluoride, the ratio of the mass of calcium to the mass of fluorine will be same.

In the first sample, the ratio of the mass of calcium to the mass of fluorine is

Let w g of calcium were formed from second sample. 165 mg of fluorine corresponds to 0.165 g of fluorine.

Hence, 0.175 g of calcium were formed from decomposition of second sample.

Could you please show me the steps on how you did this? I claim that more than 70% of my students pass my class. You do not believe me, so you do a records request to the college and find out that 85 out of 125 of my students passed my class last semester. Test at the 0.01 level of significance that my proportion of passing students is not really 70%. Thank you!
