Explanation:
- Write the skeleton and balance the given equation
#Ca(OH)_2(s)+CO_2(g)>CaCO_3(s)+H_2O(g)# - Find the molar mass of
#CaCO_3# as the involved compound as specified in the problem.
#=(100g)/(mol)# - Since the given data is already expressed in
#mol# , conversion per convention is no longer necessary in this case. - Referring to the balanced equation shown above for the mole ratio, find the
#etaCaCO_3# through molar conversion; i.e.,
#=0.962cancel(molCa(OH))_2xx(1molCaCO_3)/(1cancel(molCa(OH)_2))#
#=0.962molCaCO_3# - Now, find the
#"mass"(m)# of#CaCO_3# , knowing the#etaCaCO_3# as computed, and the molar mass of the compound for the conversion.
#=0.962cancel(molCaCO_3)xx(100gCaCO_3)/(1cancel(molCaCO_3))#
#=96.2gCaCO_3#
