2 NI₃= N₂ + 3 I₂

2 x 394.71 g --------------- 3 x 253.80 g
3.58 g ---------------------- ( mass  of I₂ )

3.58 x 3 x 253.80 / 2 x 394.71 =

2725.812 / 789.42 => 3.4529 g of I₂

1 mole I₂ --------------- 253.80 g
?? ----------------------- 3.4529 g

3.4529 x 1 / 253.80 => 0.0136 moles of I₂

Answer C

hope this helps!

How many liters of laughing gas are in 0.98 moles stp
Alex73 [517]

By applying ideal gas equation,

[tex]P\times V=n\times R\times T[\tex]

Where, P= pressure of gas

V=volume of gas

R=Gas constant

n=Number of moles of gas

T=Temperature

At STP, each gas has a defined value of pressure, volume and temperature.

P= 1 atm

R=0.0821 L atm mol⁻¹ K⁻¹

T= 0°C or 273 K

Putting all the values in the equation will give:

[tex]1\times V=0.98\times 0.0821\times 273[\tex]

V = 22 L

So the answer is 22 L.
