Compounds are weighed using scales to yield grams. It's often necessary to convert grams to moles for chemistry calculations.Peter Muller / Getty Images Learn how to convert the number of grams of a molecule to the number of moles of the molecule with examples below. This type of conversion ...
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
Chemists have a variety of means at their disposal to communicate the concentration of chemicals in solution. One common method of describing concentration is to give the moles chemical per liter solution, or the molarity. A mole is a term which stands for 6.02 x 10^23 atoms or molecules of...
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 ...
A liter is 10 times more volume than a deciliter, so multiply mg/dl by 10 to get mg/l. Determine the ratio to convert milligrams of cholesterol to millimoles (mmol) of cholesterol. The ratio of milligrams to millimoles is equal to the ratio of grams to moles. You therefore need to ...
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/...
How will you convert benzene to m-dinitro benzene ? View Solution How will you convert benzene into Benzene sulphonic acid ? View Solution How Phenol is converted to Benzene ? View Solution Each mole of benzene reacts with ___ moles of chlorine to give hexachlorobenzene. View Solution ...
Concentrations are in moles/liter (M). The higher the Ka for an acid, the stronger the acid. pKa: pKa can be used to see how strong an acid is and can be calculated as follows: pKa=−log10Ka Likewise, if the pKa is known, the Ka can be calculated as follows: Ka=10−...
What is a mole, and how do you convert from grams to moles? How does this relate to Avogadro's number? Mole: Mole is a technical term that is used to explain how much mass of material contain 6.023×1023 (Avogadro's number) atoms. In other words,...
order that they cancel and leave us with the units we want. So, in the present problem, we have M which has units of moles/liter and we have mls which we will convert to liters. Then we will also have to change moles to millimoles (mmole) since that's what the question asks ...
