The great divide side, you will divide. Zinc (Zn) is used to form a corrosion-inhibiting surface on galvanized steel. I have had the pleasure to work varied careers including a stint as an analytical chemist, forensic scientist, lab creator at a big microbrewery (oxymoron? Show that the law of conservation of mass is observed. Sign in What volume of C6H6 (l) contains 5.64 X 10^22 atoms of C? Start with the given: 5.64 X 10^22 atoms of C x 1 mole of C/6.02 X 10^23 atoms of C … That number of particles is Avogadro's Number, which is roughly 6.02x1023.
This might sound like us being "big headed" but we have a bowl's green at work - however we have never been able to use it as one due to the fact there are so many mole hills. Mass to moles- divide by the molar mass. 3. Get the free "Mole Calculator" widget for your website, blog, Wordpress, Blogger, or iGoogle.
We had them "sorted" and the mole holes levelled out, only for us to come back after the weekend to around 20-30 mole hills again! 1- McGraw-Hill Ryerson - High School Chemistry 11 v4.pdf - Google Drive. A mole of chemistry teachers is 6.02x1023chemistry teachers. The mole digs a series of connecting tunnels, pushing up the soil onto the surface (the mole hills).

Moles are small mammals adapted to a subterranean lifestyle (i.e., fossorial).They have cylindrical bodies, velvety fur, very small, inconspicuous ears and eyes, reduced hindlimbs, and short, powerful forelimbs with large paws adapted for digging. 5 years ago. (density of C6H6 (l)=0.877g/mL) Please show your work! Users can search by subject and grade level. When the mole is used, the elementary entities need not be molecules, but they must always be specified. PhET, based at the University of Colorado at Boulder, offers over four dozen chemistry-based simulations.

Hello and welcome to John Borlik's Chemistry Pages! 3 Answers. Sign in The mole is defined by international agreement as the amount of substance (chemical amount) of a chemical system that contains as many molecules or entities as there are atoms in 12 g of carbon-12 (12 C). It is commonly known as a mole hill.
