What is the volume of 45.6 g of silver if the density of silver is 10.5\ rm{g/ml}? What is molarity in analytical chemistry? What volume must 25 ml of 95% by mass of a solution H2SO4,density 1.80 g/ml, be diluted to produce 0.5 M solution?
What is a molecule? A molecule is two or moreatomsconnected by chemical bonds, which form the smallest unit of a substance that retains the composition and properties of that substance. Molecules form the basis of chemistry. Molecules are noted with theelementsymbol and a subscript with the num...
In the March-April 2009 issue of Chemistry International , Ian Mills and Martin Milton reviewed concepts familiar to chemists: the quantity amount of substance and its unit, the mole. They also presented a possible new definition for the mole. The reasoning behind the possible new definition is...

Key Takeaways: Mole in Chemistry The mole is anSI unitused to measure the amount of any substance. The abbreviation for mole is mol. One mole is exactly 6.02214076×1023particles. The "particles" could be something small, like electrons or atoms, or something large, like elephants or stars....
In a chemical reaction, compounds react in a set ratio. If the ratio is unbalanced, there will be leftover reactant. To understand this, you need to be familiar with the molar ratio ormole ratio. Mole Ratio The mole ratio compares the number of moles in a balanced equation. ...
