Mole Concept

Mole concept is a method to determine the amount of any substance that consists of some elemental particles using a grouping unit called ‘mole’. The mole concept enables one to handle the large amount of small elementary particles. The mole concept can be used in many calculations related to mole calculation, molar amount, mole ratio, and so on, which are significant in chemistry.

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...
