While it is important to understand moles and the number of atoms and molecules, a more practical unit for experiments is the gram, which is a unit of mass. You cannot measure a mole of a substance in a laboratory, but you can measure its mass in grams on a balance. The conversion fa...
Mole to Gram Conversions:Many times chemists are interested in the number of atoms that react in a chemical reaction. Atoms are very small, so reactions use many of them resulting in a large number. To simplify this, chemists use the mole which is equal to 6.02×1023 atoms...
Atoms were once thought to be the smallest building blocks of the universe, until it was discovered that even they were constructed of building blocks of their own. Those building blocks are protons, electrons and neutrons, and with the advancement of science it has been discovered that each of...
The particles can either be atoms, ions or molecules. The molar mass is the mass of one mole of a substance. Answer and Explanation: 1 Step 1: Use the molar mass of C4H10 to determine the moles in 3.33 g of C4H10 Since the molar mass of {eq}\rm......
How to Calculate the Molar Mass More Details on the Calculation Definition The molar mass can be defined as the mass of one mole of any substance. As for a mole, that’s just the overall number of atoms in twelve grams of the carbon-12 isotope. That’s always a fixed number, often ...
A group of magic mushrooms are shown in a growbox. farmer images/Getty Images Mushrooms are adored around the world as food sources. Many species are used to give an earthy flavor and meaty texture to everything from pizza to risotto. But if you consume a certain type of mushrooms, that...
Omega-3 fatty acids are harder to find. Things like flax seeds, pumpkin seeds and walnuts are high in omega-3 fatty acids, as are salmon, trout and tuna. Current thinking is that these two fats need to be balanced in the diet at a ratio like 1-to-1 or 2-to-1, rather than the...
Measurement refers to the act of determining the physical characteristics of a given object- such as length, volume, and mass- for a given purpose. Making precise measurements is very important for many purposes, including commerce and in the natural sciences. Hence, systems of measurem...
All the rest of the graphs in this section are pretty much flat. Overall they slope a teeny bit in a promising direction - blood pressure is the best of these, but blood pressure isn't what this study is supposed to be about; measure enough things and you're guaranteed to findsomething...
Everyone knows the story of the Trojan horse. The Greeks hid a small force of their warriors in the belly of a great wooden horse. Then they wheeled the horse to the gates of Troy and said, "Yo, dudes, we give up. Before we take off, please accept this noble steed as our gift to...
