Ammonium phosphate (NH,),PO,) is an important ingredient in many solid fertilizers. It can be made by reacting aqueous phosphoric acid (H,PO,) with liquid ammonia. Calculate the moles of ammonium phosphate produced by the reaction of 0.065 mol of phosphoric acid. Be sure your answer has a unit symbol, if necessary, and round it to 2 significant digits.

1 _ 02>_CO2 +_H20 1)_CsHs +, 6.003g of oxygen, makes how many moles of water?

If the crucible originally weighs 3.715 g and 2.000 g of hydrate are added to it, what is the weight of the water that is lost if the final weight of the crucible and anhydrous salt is 5.072?  Do not include units and assume three decimal places for all numbers.  Remember to include the zero before the decimal if the number is less than one.

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

Ammonium perchlorate NH4ClO4 is a powerful solid rocket fuel, used in the Space Shuttle boosters. It decomposes into nitrogen N2 gas, chlorine Cl2 gas, oxygen O2 gas and water vapor, releasing a great deal of energy. Calculate the moles of water  produced by the reaction of 0.70mol of ammonium perchlorate. Be sure your answer has a unit symbol, if necessary, and round it to 2 significant digits.
