In chemistry, a mole is a quantity used relate reactants to products in stoichiometric equations. A mole of any substance is equal to 6.02 x 10^23 particles -- usually atoms or molecules -- of that substance. For a given element, the mass (in grams) of o
Chemistry is full of many different confusing conversions. These conversions are important because they ultimately allow us to discover how a particular atom or molecule will interact with other atoms and molecules. Central to chemical conversions is the conversion of grams to moles, and vice versa....
This relates to the fact that chemicals react with each other not on the basis of mass but on the basis of the ratio of individual "pieces," regardless of size. The concept of moles and equivalents, and thus millimoles and milliequivalents, underlies this relationship, and it is of vital...
High School Tutor Specializing in Chemistry & English See tutors like this The concentration of a solution is, in other words, how much solute is in a solution. Molarity is one way to depict concentration, as it is the measure of moles of solute over liters of solution. Molari...
Step 2: Divide moles by liters to get molarity. {eq}Molarity=\frac{moles\: of\: solute}{liters\: of \: solution}= \frac{0.00035}{0.050}=0.007\: M {/eq} If we want to round this to the correct number of significant figures we need to add a significant zero making it 0.0070...
Now, the units are g/L, and you can use the molar mass to convert to mol/L: (0.258 g NaOH/1 L)x(1 mol/39.997 g NaOH) = 0.00645 mol NaOH/1 L. Finally, you can convert from moles to millimoles. There are 1,000 millimoles in 1 mole: (0.00645 mol NaOH/1 L)x(1000 mmol/...
Stoichiometry is an important field in chemistry that deals with quantities of chemical reactants and products in chemical reactions. The specific quantity or units vary but can include moles, mass, number of particles (atoms, molecules, ions, etc.), and more or conversion between some of ...
