thanks for all this help! so for this one, 1 - it would be 0.108 x 35.7 = 3.86 moles of Na2CO3 2 - 2.86 moles Na2CO3 / 2 Moles HNO3 = 1.93 Moles HNO3. 3 - 1.93 Moles HNO3 x 0.150 M HNO3 = 0.290 L which would equal 290 mL. Is this the final solution? 4 - I need help with this ...

my teacher insists that we do it that way, i don't really understand it but i try! so it would come out to be 0.026 moles Pb(NO3)2. Then, converting Pb(NO3)2 into KCl it would come out to be 0.052 Moles KCl. Then divide 0.052 by 0.150 which would equal 0.15 L?
June 21, 2010

chemistry
okay so the solution would be. 0.150 M KCl x 0.175 M Pb(NO3)2/ 1 M KCL x 0.150 L/0.175 M Pb(NO3)2 = 0.023 L?
