how many grams of ammonium carbonate are needed to decompose in order to produce 6.52 g of carbon dioxide?
defon

Answer:

<u>= 14.24g of </u>(NH4)_{2}CO_{3}<u> is required.</u>

Explanation:

Reaction equation:

(NH4)_{2}CO_{3} → 2NH_{3} + CO_{2} + H_{2} O

Mole ratio of ammonium carbonate to carbon dioxide is 1:1

1 mole of CO2 - 44g

?? mole of CO2 - 6.52g

= 6.52/44 = 0.148 moles was produced from this experiment.

Therefore, if 1 mole of (NH4)_{2}CO_{3} - 96.09 g

0.148 mol of (NH4)_{2}CO_{3} --  ?? g

=0.148 × 96.09

<u>= 14.24g of </u>(NH4)_{2}CO_{3}<u> is required.</u>
