Question

For the chemical reaction 2 AgNO, + Na,co. — Ag,cro, + 2 NaNO, how many moles of silver chromate will be produced from 98.0 g of silver nitrate? moles of silver chromate: mol hel

Answer 1

Number of moles of AgNO3 = 98.0 g / 169.87 g/mol = 0.577 mole

From the balanced equation we can say that

2 mole of AgNO3 produces 1 mole of Ag2CrO4 so

0.577 mole of AgNO3 will produce

= 0.577 mole of AgNO3 *(1 mole of Ag2CrO4 / 2 mole of AgNO3)

= 0.289 mole of Ag2CrO4

Therefore, the number of moles of Ag2CrO4 = 0.289
