First, make sure to balance your equation.

3H2(g) + N2(g) ⇄ 2NH3(g)

Now, you can write your Kc expression. Remember that Kc is products over reactants, and the exponent for each product or reactant is based on its coefficient.

Kc = [NH3]^2 / [H2]^3[N2]

Pb(NO3)2<br> how do i solve this
Sindrei [870]

You can see the periodic table one by one.

Pb(NO3)2 = PbN2O6

So there are

1Pb

2N

6O

and so you find the molecular mass from the periodic table and add all the numbers

Molacular mass of

Pb = 207

N = 14

O = 16

multiply it with the number of atoms

1Pb = 207 × 1 = 207

2N = 14 × 2 = 28

6O = 16 × 6 = 96

Molecular mass total = 207 + 28 + 96 = <u>3</u><u>3</u><u>1</u>

So the molecular mass is 331.
