When sodium, a soft metal, is combined with chlorine, a poisonous gas, salt is formed. The hydrogen atoms were drawn larger than the oxygen atom The hydrogen atoms were shown to be various sizes There was one less hydrogen atom There was one more oxygen atomĢ4 Let’s review… 2. Homogeneous-mixture is the same all throughout (Ex: Solutions like lemonade) Heterogeneous-mixture where particles remain physically separate (Ex: Salad, Bag of M&Ms)Ģ2 At your lab table… Look at each diagram and identify it as one of the following: 1) Element 2) Compound 3) Mixture-It can be a mixture of elements, a mixture of compounds, or a mixture of compounds and element.Ģ3 Let’s review… This model of water would be more accurate if I can differentiate between a heterogeneous and homogeneous mixture.ġ4 Types of Mixtures… Solution Colloid Suspension SOLVENT SOLUTEġ5 Solution: This is a homogeneous mixture…it’s the same all throughout. I can identify the different parts of a solution.

Identify the following as an element, compound, or mixture."- Presentation transcript:ġ BELL WORK! Identify the following as an element, compound, or mixture. Using the above calculator you could find that e.g. Or 1 mole of a substance will contain Avogadro's number of that substance. The term " mole" is defined in that one mole of a substance with a molecular (or atomic) mass of one (1), will have a mass of 1 gram. It is defined to be 1/12 of the mass of one atom of carbon-12 and in older works is also abbreviated as "amu".Īlso, important in this field is Avogadro's number (N A) or Avogadro's constant (6.0221 x 10 23). In related terms, another unit of mass often used is Dalton (Da) or unified atomic mass unit (u) when describing atomic masses and molecular masses. Molecular mass or molar mass are used in stoichiometry calculations in chemistry. This Calculator has been tested on Internet Explorer version 6 only,įirefox might not show all fields correctly.

Lenntech BV cannot be held responsible for errors in the calculation, Make sure you enter the molecule of crystallization at last (e.g. The calculator handles at most two different bracket levels. The molecular mass calculator will recognize the entered formula's, which are included in the list of organic compounds.
IDENTIFY THE FOLLOWING AS ELEMENT COMPOUND OR MIXTURE SERIES
Or you can choose by one of the next two option-lists, which contains a series of common organic compounds (including their chemical formula) and all the elements. This online calculator you can use for computing the average molecular weight (MW) of molecules by entering the chemical formulas (for example C3H4OH(COOH)3 ).
