Happy November!


Happy Halloween!!! Come to Mathnasium of Fairfax today for a Halloween surprise!


This past Saturday was MASTERY CHECK RAFFLE DAY! Winners will receive a goodie bag!


It’s a big day for chemistry (and math!) enthusiasts—today, October 23ʳᵈ, is 𝑵𝒂𝒕𝒊𝒐𝒏𝒂𝒍 𝑴𝒐𝒍𝒆 𝑫𝒂𝒚!

In chemistry, a 𝙢𝙤𝙡𝙚 is a unit of measurement that describes a quantity of anything! While you could 𝘤𝘰𝘯𝘤𝘦𝘪𝘷𝘢𝘣𝘭𝘺 have a 𝙢𝙤𝙡𝙚 of water molecules, a 𝙢𝙤𝙡𝙚 of chocolates, or a mole of whales—anything countable, really—a 𝙢𝙤𝙡𝙚 is a very, 𝘃𝗲𝗿𝘆 𝗹𝗮𝗿𝗴𝗲 quantity.

One 𝙢𝙤𝙡𝙚 is equal to 𝟲.𝟬𝟮𝟮𝟮𝟱∙𝟭𝟬²³ particles of the substance you’re counting. That’s a lot of 𝘴𝘵𝘶𝘧𝘧, which is why the 𝙢𝙤𝙡𝙚 is used by chemists exclusively in reference to things that are very small, such as the number of molecules of chemical compounds or the number of atoms of a given element.

𝟲.𝟬𝟮𝟮𝟮𝟱 ∙ 𝟭𝟬²³ is referred to as 𝘼𝙫𝙤𝙜𝙖𝙙𝙧𝙤’𝙨 𝙉𝙪𝙢𝙗𝙚𝙧, named for 19ᵗʰ century Italian chemist 𝘼𝙢𝙚𝙙𝙚𝙤 𝘼𝙫𝙤𝙜𝙖𝙙𝙧𝙤, whose theories laid the groundwork for atomic theory.
