Did you know?
Did you know that you can calculate the number of moles of calcium chloride (CaCl2) that can be obtained from a given mass of limestone (CaCO3)? In this case, let's consider 25kg of limestone. By using the atomic masses of calcium (Ca=40), carbon (C=12), oxygen (O=16), hydrogen (H=1), and chlorine (Cl=35.5), you can perform the necessary calculations. First, convert the mass of limestone to moles by dividing it by the molar mass of CaCO3, which is (40+12+3(16)=100 g/mol. Then, since CaCO3 reacts with HCl to form CaCl2, you can use the balanced chemical equation to determine the stoichiometry of the reaction. From this information, you can find the number of moles of CaCl2 that can be obtained. Remember, understanding the stoichiometry and molar mass of compounds allows scientists to perform these calculations and predict the outcomes of chemical reactions.
