Checking Normality of Numerical, and Categorical Data
WebFind the normality of 0.321 g sodium carbonate in a 250 mL solution. To solve this problem, you need to know the formula for sodium carbonate. Once you realize there are two … Webi.1mole(44g) of CO 2 contains 12g of carbon.. 3.38 g of CO 2 will contain carbon = (12g/44g) x3.38g =0.9217g. 18g of water contains 2g of hydrogen. Therefore 0.690g of water will contain hydrogen=2g/18gx 0.690 =0.0767 g. Since carbon and hydrogen are the only constituents of the compounds, the total mass of the compounds is: Web11 de abr. de 2024 · The Normality formula describes the capacity of accepting or donating the number of electrons that an oxidizing or the reducing agent can manage, in a redox reaction.
