What is the molar mass of chlorine gas? What is the molar mass of calcium nitrate? What is the molar mass of PbI2? What is the mass in grams of 2.4e-2 mol K2SO4? What is the molar mass of KOH? What is SO3's molar mass?
Molar mass is the number of grams of a substance that equals one mole or6.02x1023molecules, also known as Avogadro's number. Molar mass can be used to convert between moles and grams, denoted byg/mol. Answer and Explanation: KMnO4

Or simply concentration could be expressed in units of mass per volume (i.e., g/L, mg/L). We can divide the substances that dissolve in water into two broad classes, electrolytes and nonelectrolytes. An electrolyte is a substance that dissolves in water to give ions that make the ...
Molar Mass You need to calculate molar mass if you have more than one atom in a problem. It’s easy… just add the masses together and multiply time the number of atoms in the molecule (subscript) For example: H2O Hydrogen =1 Oxygen =16; There are 2 hydrogens and 1 oxygen so the ...
Molar mass is the mass of one mole of a substance. We determine the molar masses from values on the periodic table. Answer and Explanation: Before we can sum all of the molar mass of the elements in acetic acid we need the chemical formula of acetic acid. Acetic acid's chemical formula...
