For the blanks in this question: Report here only your numerical answers (without units), if the value is less than zero as a decimal (not in scientific notation), to the correct number of significant figures.

Mg(OH)2 (molar mass:  58.32 g/mole)

Al(OH)(molar mass:  78.00 g/mole)

  1. How many moles Mg(OH)2 are present in the tablet? 
  2. How many moles of Al(OH)3 are present in the tablet? 
  3. How many moles of HCl are required to neutralize the Mg(OH)2 in the tablet?    Start this question by using your rounded answer from #1.
  4. How many moles of HCl are required to neutralize the Al(OH)in the tablet?    Start this question by using your rounded answer from #2.
  5. How many moles of HCl acid will be required to neutralize both the Mg(OH)2 and the Al(OH)3 in the tablet?    Use your rounded answers from #3 and #4 to answer this question.
  6. How many milliliters of 0.200 M HCl can be neutralized by one tablet?    Use your rounded answer from #5 to answer this question.
