Answer:
132 amu
Explanation:
ammonium sulphate is
to calculate molecular weight we need
atomic weight of the element of the compound
here ammonium sulphate is formed by two elements
2 nitrogen , 8 hydrogen , 1 sulphur amd 4 oxygen
atonomic number of nirogen is 14 , hydrogen is 1 , sulphur has 32 and oxygen has 16
so lets calculate molecular weight of ammonium sulphate
2*14 + 8*1 + 1*32 + 4*16
28 + 8 + 32 + 64
132 amu
Answer:
Kc = 1.35x10^7
Explanation:
Let's write the reaction again:
2R + A <------> 2Z Kp = 5.51x10^5
In order to know the value of Kc, we need to write the expression that relations the Kp with Kc which is:
Kp = Kc * (RT)^Δn (1)
Where:
R: 0.082 L atm/ K mol
Δn: difference between the coefficients of the reaction
Kc: equilibrium constant
T: temperature in K
Now, from the equation (1) we can solve for Kc:
Kc = Kp / (RT)^Δn (2)
Now, before do any calculations, let's do first the value of Δn:
Δn = 2 - (2+1) = -1
Now, replacing all values in (2):
Kc = 5.51x10^5 / (0.082*298)^-1
Kc = 1.346x10^7
The third option is the correct one.
