A 1 M solution is said to be “one molar”. Two solutions that have the same molarity will have the same number of molecules of the chemical per liter but are likely to contain differing masses of that ...

The formula mass of each reactant or product can be used to calculate the reacting masses. Calculate the mass of aluminium formed when 51 g of aluminium oxide are electrolysed. Firstly ...

Students will be able to make measurements showing that whether the process is a change of state, dissolving, or a chemical reaction, the total mass of the substances does not change. Note: In the ...

Note: We are purposely using the terms “size” and “amount” instead of “volume” in this lesson about density. We are also using “heavy”, “light”, and “weight” instead of “mass”. If your students have ...

The Law of Conservation of Mass dates from Antoine Lavoisier's 1789 discovery that mass is neither created nor destroyed in chemical reactions. In other words, the mass of any one element at the ...

One nanomolar is equivalent to 10-9 molar, or one billionth of a molar. In practical terms, this means that a nanomolar solution contains one nanoparticle, molecule, or entity of interest per liter of ...

The molar volume is the volume occupied by one mole of any gas. The same value is obtained for all gases at the same temperature and pressure. The value of the molar volume will be different for ...

But what's an atom made of? What is matter, really? Matter is defined as that which 1) has mass and 2) has volume or takes up space. Mass is an intrinsic property whose base SI unit is the ...

Mass spectrometry is an analytical technique that uses an instrument called a mass spectrometer to measure the mass-to-charge ratios of molecular ions. Molecules fragment within the mass ...

Jennifer Simonson draws on two decades as a journalist covering everything from local economic developement to small business marketing. Beyond writing, she tested entrepreneurial waters by ...
