Question

what mass of lead || trioxonitrate(v) would be required to yield 12g of lead || chloride on the addition of excess sodium chloride solution (pb=207,N=1,o=16,Na=23,cl=35.5) pb(No)+2Nacl pbcl+2NaNo

Answer 1

That chemical with the funny name is properly called lead(II) nitrate.

Pb(NO3)2 + 2NaCl ==> PbCl2 + 2NaNO3.

mols PbCl2 needed = grams/molar mass = ?
You get 1 mol PbCl2 for every 1 mol Pb(NO3)2 used initially.
Then grams Pb(NO3)2 = mols Pb(NO3)2 x molar mass Pb(NO3)2 = ?

Post your work if you get stuck.

Answer 2
