Answer:
The mass of nitrogen molecule = 45.65 g
Explanation:
The equation for the redox reaction can be represented as follows:
We know that:
numbers of moles = mass/molar mass
For :
number of moles = 50g/92 g/mol
number of moles = 0.5435 mol
For :
number of moles = 45 g/ 32 g/mol
number of moles = 1.40625 mol
From the above equation;
number of moles of needed = 1/2 moles of
= 1/2 × 1.40625 mol
= 0.703125 mol
The amount of present = 0.5435 moles which is less than the needed. As such
is the limiting reagent
The number of moles of nitrogen molecule produced = 3 × (
)
= 3 × 0.5435
= 1.6305 mol
The mass of nitrogen molecule = number of moles of
× molar mass of
The mass of nitrogen molecule = 1.6305 mol × 28 g/mol
The mass of nitrogen molecule = 45.654 g
The mass of nitrogen molecule = 45.65 g
