AN an antacid tablet contains 0.1g of magnesium hydrocarbonate, what nass of stomach acid, HCL, will it neutralise?
Wine is made by the fermentation of the sugar in grapes.
Whta massof ethanol can be obtained from 6.00kg of sucrose?
You would do better to post one problem per post.
#1.Write the equation.
Mg(HCO3)2 + 2HCl==>MgCl2 + 2H2O + 2CO2
Convert 0.1 g Mg(HCO3)2 to mols.
Convert mols Mg(HCO3)2 to mols HCl using the coefficients in the balanced equation.
Convert mols HCl to g using g = mols HCl x molar mass HCl.
#2. Write the equation.
C6H12O6 ==>2C2H5OH + 2CO2
Convert 10 kg sucrose to mols.
Convert mols sucrose to mols ethanol using the coefficients in the balanced equation.
Convert mols ethanol to g ethanol using mass = mols ethanol x molar mass ethanol.
Check my work. Check my thinking.
