Thank you for the answer, but I'm confused for part b why do you multiply by 2? Isn't it 1 mol of Na2CO3 for every 2 moles of AgNO3? If that's the case wouldn't you divide by 2 like in part a? Cause I tried it mself, got 0.03 moles AGNO3 like answer... My Stoichiometry Calc...0.03 moles AGNO3 x (1 mol Na2CO3)/(2 mol AgNO3) x (105.99 Na2CO3)/(1 mol Na2CO3)=1.5898g I don't think my calc is correct answer but confused why multiply by the 2 instead...
