Please I have waited two weeks to receive help. Please help me with my science homework. Plesse

Question

1.) S   + 6 HNO3 --> H2SO4 + 6 NO2 + 2 H2O

In the above equation how many moles of water can be made when 163.6 grams of HNO3 are consumed?

Round your answer to the nearest tenth. If you answer is a whole number like 4, report the answer as 4.0

Use the following molar masses. If you do not use these masses, the computer will mark your answer incorrect.:

Element	Molar Mass
Hydrogen	1
Nitrogen	14
Sulfur	32
Oxygen	16

2.) 3 Cu + 8HNO3 --> 3 Cu(NO3)2   + 2 NO + 4 H2O

In the above equation how many moles of water can be made when 118.6 grams of HNO3 are consumed?

Round your answer to the nearest tenth. If you answer is a whole number like 4, report the answer as 4.0

Use the following molar masses. If you do not use these masses, the computer will mark your answer incorrect.:

Element	Molar Mass
Hydrogen	1
Nitrogen	14
Copper	63.5
Oxygen	16

please helps please

Answer 1

(1) using the numbers in the table find the molecular mass of HNO3 (call this x)

(2) find the number of moles of HN03 - this will be 163.6 / x - call this y

(3) from the equation 6 moles HNO3 gives 2 of H20

so 1 mole HNO3 gives (2/6) moles H20

so y moles HNO3 gives (2/6) y moles of H2O
