Answer:
Pascal is the most common unit for measuring pressure
The average sea level pressure is 1013 mbar
Answer: N2(g) + 3H2-> 2NH3(g) This is the balanced equation
Note the mole ratio between N2, H2 and NH3. It is 1 : 3 : 2 This will be important.
moles N2 present = 28.0 g N2 x 1 mole N2/28 g = 1 mole N2 present
moles H2 present = 25.0 g H2 x 1 mole H2/2 g = 12.5 moles H2 present
Based on mole ratio, N2 is limiting in this situation because there is more than enough H2 but not enough N2.
moles NH3 that can be produced = 1 mole N2 x 2 moles NH3/mole N2 = 2 moles NH3 can be produced
grams of NH3 that can be produced = 2 moles NH3 x 17 g/mole = 34 grams of NH3 can be produced
NOTE: The key to this problem is recognizing that N2 is limiting, and therefore limits how much NH3 can be produced.

Answer:
200 ppm
Explanation:
Sodium nitrate is used as a preservative in hotdog to preserve the colour of meat. 200 ppm of sodium nitrate (NaNO3) can be used in a hot dog. A human body can accept 3.7 mg of Sodium nitrate as per kg weight of body. So, excessive use of sodium nitrate in hot dog can harm the human body and produce diseases.
