Question

Please help!!

S + 6 HNO3 --> H₂SO4 + 6 NO₂ + 2H₂O

In the above equation how many moles of water can be made when 158.3 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.:

Hydrogen 1
Nitrogen 14
Sulfur 32
Oxygen 16

Answer 1

Mr of HNO3= 1+14+(16x3) = 63

Mole= mass/ Mr

158.3G/63=2.512698413

1 moles of 6 moles of HNO3 = 2.51… / 6 = 0.4187830688

2 moles of water= 0.4187830688 x 2 = 0.8375661376

Answer to 1 d.p = 0.8 moles
