Hi can someone please tell me if I’m tripping or is the mass of H2 =1.03g here wrong

Cuz isn’t the Mr of H2 here (4 times 1.01)
Since there are 4 H produced.

So isn’t it 0.1016moles times (4*1.01) = 0.41046g
So why is the answer 1.03g?
Pls help me make sense thank u!

Quite a lot of errors in the question... note that mass = moles x molar mass. Moles of H2P to H2 is 2: 1
