What is it meant by relative formula mass? How is it calculated using the periodic table? Each element has a relative atomic mass. When a compound is made‚ these relative atomic masses are added together to calculate the relative formula mass of the substance. For example the atomic mass of Na is 23 and the atomic mass of Cl is 35.5 so the relative formula mass of NaCl is 58.5 How by using RFM is it possible to work out amounts of a substance in terms of moles? The compound I was using in my

The "XxXX" formula You have probably noticed a recurrent formula in binocular jargon‚ a formula such as 8x35 or 10x60. This refers to the concrete optical capabilities of the instrument. The number before the "x" represents the magnification power‚ while the number after the letter represents the aperture (or diameter) of the objective lens in millimeters. So a 8x35 binocular‚ for example‚ features a 35 mm lens and can make objects appear eight times closer to you. A 10x50 lens brings things 10

relation to the mass of the crystalline structure. This water that is trapped inside the hydrated solid structure is called water of crystallization or water of hydration. A salt with associated water of crystallization is known as a hydrate. The formula of a hydrated salt is written as the number of moles of water present in one mole of crystalline structure. Deliquescent materials are substances that absorb water from the atmosphere and eventually become hydrated. These materials‚ usually salts

Bachelor and Spinster Balls (B&S) events are hosted regularly in rural Australia‚ known locally as "B & S Balls" or simply "B&S’s". They are staged for young (18 years and over) spinsters and bachelors and traditionally the couples dress up in formal wear.[1] Large volumes of cheap alcohol such as beer‚ spirits‚ Bundaberg Rum and Jim Beam can be consumed. The activities usually start at night and run until morning‚ but from mid-afternoon people will start to arrive and the partying/drinking will
