Question

What mass (in g) of nitrogen are needed to react completely with 5.8 g of hydrogen?

N2 + 3H2 -> 2NH3
A. 5.8g N2
B. 81 g N2
C. 76 g N2
D. 27 gN2

Answer 1

D

Step-by-step explanation:

1 mole of N2 reacts with 3 moles of H2

28 g of N2 reacts with 6g of H2

x will react with 5.8g of H2

x= (28*5.8)/6

= 27.0g
