Hey there!
Given the reaction:
P4 + 10 Cl2 ------------------ 4 PCl5
Molar mass P4 = 124 g/mol
Number of moles P4:
n = mass of solute / molar mass
n = 24.0 / 124
n = 0.1935 moles of P4
Therefore:
1 mole P4 --------------- 4 moles PCl5
0.1935 moles P4 ------- moles PCl5
moles PCl5 = 0.1935 * 4
= 0.774 moles of PCl5
Hope that helps!
Answer:
3H2+N2-> 2NH3
Explanation:
This is the balanced chemical equation for the above reaction
Answer:-
86.794 K
Explanation:-
Initial temperature T 1 = 32 C + 273 = 305 K
Initial Pressure P 1 = 49.9 KPa
New Pressure P 2 = 14.2 KPa
The Volume remains same since it is rigid.
∴V 1 = V 2 = 50.0 L
Using the relation
P 1 V 1 / T1 = P 2 V 2 / T 2
New temperature T 2 = P 2 V 2 T 1 / ( P 1 V 1)
= 14.2 KPa x 50.0 L x 305 K / ( 49.9 KPa x 50.0 L)
= 86.794 K
