Maria Reyes iLab‚ Week #3 ATOMIC WEIGHT OF MAGNESIUM LAB Introduction The purpose of this lab was to determine the atomic weight of magnesium by measuring the amount of hydrogen gas evolved when hydrochloric acid reacted with magnesium. In order to measure the atomic weight I needed to measure the amount of the hydrogen gas that was evolved in reaction to the acid of the magnesium. The reaction used was: Mg + 2HCl --> H2 + Mg2+ (aq) + 2Cl- (aq). The major findings of this experiment were that

(d) An approximate 95% con…dence interval for the number of defaults for the portfop p p(1 p)=n‚ or equivalently np 1:96 np(1 p). lio is given by: np 1:96 n Plugging in p = :119‚ and n = 50‚ we get a con…dence interval of 5:95 4:49‚ or [1:46; 10:44]. This suggests we are approximately 95% con…dent that we will see between 2 and 10 defaults in our portfolio. (e) The Binomial distribution is great for independent trials like ‡ ipping a fair coin.
