Example 3 Calculate the mass of Oxygen (O2) consumed when 3.68 mol Fe reacts according to Equation (2). Solution The problem asks that we calculate the mass of O2 consumed. As we learned in Example 2 of The Molar Mass, the molar mass can be used to convert from the amount of O2 to the mass of O2.

1.2.1: Define the term molar mass (M) and calculate the mass of one mole of a species. The molar mass (M) is the mass of one mole's worth of a substance. To find the atomic/molecular mass, multiply the amount of moles by the molar mass. 1.2.2: Atomic mass, Molecular Mass, Formula Mass

Purpose To determine the molar volume of H 2 gas at STP. Theory The molar volume of a gas is the volume in litres per 1 mole of gas. STP is standard temperature and pressure, which is, 0 o C and 101 Kpa. To calculate the molar mass, divide the number of litres by the number of moles. Procedure . 1. Weigh a 3.9 cm piece of magnesium strip. 2.Iron(II,III) Oxide Fe3O4 Molar Mass, Molecular Weight

The molar ratio used of this suspension was 1.1 M:0.6 M for Fe 3+ and Fe 2+, respectively. The nanoparticles were prepared as follows: 10 mL of ferrous chloride, 10 mL of ferric chloride and 500 μL of oleic acid were added to 100 mL of distilled water under stirring.By controlling the self-assembly of Fe3O4 NPs, the diameters of the superstructures are tuned from 32 to 64 nm. This significantly enhances the indirect transition and magnetic coupling of Fe ions, thus increasing the molar extinction coefficient of Fe3O4 NPs from 3.65 × 106 to 1.31 × 108 M–1 cm–1 at 808 nm.
