How to solve for mass in chemistry

WebNov 24, 2024 · For each element, the mass percent formula is: % mass = (mass of element in 1 mole of the compound) / (molar mass of the compound) x 100% or mass percent = (mass of solute / mass of solution) x 100% The units of mass are typically grams. Mass percent is also known as percent by weight or w/w%. WebJun 8, 2024 · Explanation: To calculate formula mass, multiply the subscript of each element in the formula by the element's atomic weight (relative atomic mass) found on the periodic table. The unit for formula mass is either u or Da (Daltons). The amu has been replaced with u, even though it is still commonly used. Example
