Molar mass H₂SO₄ = 98.0 g/mol
Volume = 1.290 L
number of moles:
153.3 / 98 => 1.564 moles
M = n / V
M = 1.564 / 1.290
M = 1.212 mol/L
hope this helps!

Explanation:
The electrolysis of nickel(II) iodide yields nickel solid and iodine gas.
In the oxidation half equation;
2I^-(aq)-------> I2(g) + 2e
In the reduction half equation;
Ni^2+(aq) + 2e -----> Ni(s)
These are the half equations of the process;
The overall equation is;
Ni^2+(aq) + 2I^-(aq)-------> NiI2

The energy of a photon is
E=hf
Where
E = Energy
h = Planck's constant (6.62607004Ă—10â’34 J s)
f = frequency of photon.
So plug in the known values
E = 6.62607004Ă—10â’34 J s * 7.03 x 10^14 1/s
E = 4.65812724x10^-19 J
Since we only have 3 significant figures, the rounded result is
E = 4.66x10^-19 J</span>
I think it’s something like 29.95g, sorry if it’s wrong long i haven’t done this in so long
