Convert 74.2 g N₂ to moles. (N₂ molar mass ≈ 28.014 g/mol)
(74.2 g) (1/28.014 mol/g) ≈ 2.65 mol N₂
According to the balanced reaction, 1 mol N₂ and 3 mol H₂ get consumed together to produce 2 mol NH₃, which means we consume up to
3 (2.65 mol N₂) ≈ 7.95 mol H₂
That is, all the N₂ is consumed and we have an excess of about 6.05 mol H₂. We end up with
2 (2.65 mol N₂) ≈ 5.30 mol NH₃
or (with NH₃ molar mass ≈ 17.031 g/mol)
(5.30 mol) (17.031 g/mol) ≈ 90.3 g NH₃
It is the force that acts between objects with zero mass
Answer:
Correct option is: A--63
Cost of the item =602 INR
Conversion fee =4%
Total bank charges =9.88 USD
The bank charges includes conversion rate and 4% conversion fee.
Let the conversion rate (in USD) be x.
∴9.88=x+0.04x
∴x=
1.04
9.88
=9.5 USD
The cost paid by the customer is INR 602 and its value in USD is 9.5.
Hence, the conversion rate is =
9.5
602
=63.36
Therefore, we can say that 1 USD =63 INR
Explanation:
Answer:
return what they heard once the customer has finished talking
Journals are more professional and specific in subject. people would would read it would be learned and interested in the exact subject, so researchers, people in that field of study, and possibly college students researching
