Mole Ratio General Chemical Formula:{eq}A_a B_b C_c ... {/eq} where the capital letters represent the atomic elements and the small letters represent the number of moles. Next, we will look at two examples of chemical formulas and we will work through how to calculate the mole ratio...
So, the moles of the substance is equal to the ratio of the total mass of the substance to its molar mass. The formula is given below: {eq}Moles = \dfrac{mass}{molar\, mass} {/eq}Answer and Explanation: We are given 2.070 g of water. To find the moles of ...
the mole fraction of the solvent = moles of solvent / total moles. Besides, in some cases, the mole number is not given directly. So, you have to find it using the chemical formula of the compounds their weight or their volumes.
Example: You analyze a compound and find that it contains 0.675 g of hydrogen (H), 10.8 g of oxygen (O) and 13.5 g of calcium (Ca). What is the empirical formula?1. Find the Number of Moles of Each Element The molar mass of hydrogen is 1 g (rounding to one decimal place), so...
