Question

The following questions involve the quantities of some materials you will be using in the calorimetry lab. Keep a copy of your answers, so you will not have to recalculate them in the lab. (a) How many moles of NH3 will you be using in Part C of the calorimetry experiment?

Answer 1

Answer:

0.075 moles

Explanation:

 Molarity = Mass/ Molar Mass*1000/Volume(ml)

Mole = Mass/ Molar mass

Given

  Molarity = 1.50 moles/ml

  Volume = 50 ml

∴ moles = Molarity*Volume/1000

              =1.50 *50  / 1000

              =0.075 moles
