The mass in grams of one mole of substance is called molar mass. Each element has its own unique molar mass. For example, carbon’s molar mass is 12.011 g/mol, and magnesium’s molar mass is 24.3050 g/mol. Solution for What is the molar solubility of barium oxalate(BaC2O4) in a solution buffered to a pH of 6.65? The Ksp for BaC2O4 is 2.3 x 10^-8 and the Ka's for… Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12) 몰질량은 ( molar weight ) 어떤 물질이 1몰 있을때의 질량을 이야기 하고 단위는 g/mol입니다. The molar mass of any substance is its atomic mass, molecular mass, or formula mass in grams per mole.
