Answer the following questions regarding this chemical reaction: Cu(s) + HNO3(aq) --> Cu(NO3)2(aq) + H2O(l) + NO2(g) a. If you have 32.5 g of Cu, how much Cu(NO3)2 is produced? Use the correct number of significant figures.

You are a researcher working in a famous molecular biology lab. You will be doing a very important experiment tomorrow and need to get ready by preparing several solutions. One of the solutions you will need to make is a stock solution of 3M magnesium chloride. Since you will need to use this solution many times, you decide to make 350 mL of this solution. You take out your container of magnesium chloride solid and take it to the balance. How many grams would you weigh to make 300 ml of this 3M stock solution? Atomic weight of Mg = 24.31 Atomic weight of Cl = 35.45 Write your answer with two digits past the decimal point.  (Important - Trailing zeroes count as digits - (e.g. 12.00 counts as two digits past the decimal point). The answer is ___________________________ grams 85.5 g is not the correct answer
