The mass of bismuth carbonate that decomposed is 0.445 g


calculation

write the equation for reaction


that is Bi2(CO3)3 → Bi2O3 +3 CO2



find the moles of of CO2 formed


At STP 1 mole of a gas = 22.4 L

what about 50 Ml


convert the Ml to Liters = 50/1000= 0.05 L


moles of CO2 formed is therefore= 1 mole x 0.05 L/22.4 l =2.232 x10^-3 moles


by use of reacting ratio between Bi(CO3)3 to CO2 which is 1:3 the moles of Bi(CO3)3 is = 2.232 x10^-3 x1/3= 0.744 x10^-4 moles of Bi(CO3)3


mass of Bi(CO3)3 = molar mass x number of moles


mass= 0.744 x10^-4 moles x 597.99 g/mol = 0.445 grams
