What mass of (NH4)2CO3 will produce 3 mole of sufficient acid ? . Pls give the chemical reaction and tell how to identify from given salts which acid will be produced ?
Dear student,The reaction goes as follows:[\left ( NH_{4} \right )_{2}CO_{3}\rightarrow 2NH_{3}+H_{2}O+CO_{2}]The combination of water and carbon di oxide gives carbonic acid.Hence for producing 3 moles of carbonic acid, we need 3 moles of [\left ( NH_{4} \right )_{2}CO_{3}]The molar mass of [\left ( NH_{4} \right )_{2}CO_{3}] is equal to:[\left (14+1\times 4 \right )\times 2+12+16\times 3=36+12+48=96 g/mol]Hence, the mass required would be equal to:96 [\times] 3=288 gRegardsSumit
