8.1 Molar Mass The molar mass (molecular weight) of a hydrate can be determined from its crystal structure and the degree of saturation. The molar mass of the hydrate, M, is given by: (8.1)M=NWMW+∑j=1c∑i=1nYijνiMjNW+∑j=1c∑i=1nYijνi where NW is the number of water mole...
Ammonium is a positively charged polyatomic ion, and nitrate is a negatively charged polyatomic ion. We need one of each of these ions to make a neutral compound.Answer and Explanation: The molar mass of ammonium nitrate is 80.06 g/mole. Ammonium nitrate has the formula NH4 NO3. We need...
What is the molar mass of NaOH?How to Calculate Molar Mass:Looking at the periodic table of elements, molar mass is the number below each element. It is given in grams per mole (grams / mole), where 1 mole is 6.02 x 102 atoms of said element. In other words, molar mass of an ...
Atomic Mass and Molar Mass The periodic table lists the atomic mass and molar mass of each element. The values are the same, but their units are different. Atomic mass has the units atomic-mass-units, or AMU. Molar mass is the mass of one mole of the element, which is the mass of ...
Effects of H2O/Na2O molar ratios (MRs) on the developed alkaline activated pozzolanic solid wastes (PMs)-ultrafine palm oil fuel ash (UPOFA) and ground blast furnace slag (GBFS)-were studied by using the constant mass of combined activators (10M NaOHaq+Na2SiO3aq of silica-modulus (Ms=SiO2...
