Have a nice day
Answer:
1.772 mols
Explanation:
Because hydrogen exists as a diatomic molecule in gaseous state, that's (H2), so then it's molecular mass is 1 ×2= 2g/mol.
we can now calculate for the number of moles, so
n=m/Mr
n=3.544/2
n=1.772mols
Answer:
D) 0 (zero)
Explanation:
There's a rule that neutral compounds (compound) without charges have oxidation of zero. Also, another formula that if two atoms of the same element make one single molecules such as diatomics molecules are O2, N2, I2, Br2 oxidation states are zero, thus here N is 0 (Zero) as well.
