Please refer to this. Here is the oxidation number of nitrogen in aluminum nitride, aln. <span>Since AlN has 0 charge and Al has +3 charge; charge for N = 0 - (+3) = -3. Hope this is the answer that you are looking for. Have a great day ahead!</span>
Hey there !
a) Pb(SO4)2 => <span> lead(II) sulfate
b) </span><span>The molar mass of this compound was calculated from the amount of atoms of each element, with its respective atomic masses
Pb = 207.2 a.m.u
S = 32.065 a.m.u
O = </span><span>15.9994 a.m.u
Therefore:
</span>Pb(SO4)2 = 207.2 + 32.065 * 2 + 15.9994 * 8 => <span>399.3252 g/mol
</span>
hope this helps!
