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
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 ...
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....
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/...

Science Chemistry Dimensional analysis Explain how to convert 25 grams to milligrams.Question:Explain how to convert 25 grams to milligrams.Conversion of Mass Units:When we want to convert a unit of mass into another unit we use conversion factors. These factors express the mass in different ...
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 ...
5. We now know P, V, R, T and can solve for n, which is the amount of water vapor in moles. This value is then multiplied by 18.02 – the molecular weight of water – to give the answer in grams. 6. Summary: The formula for absolute humidity is derived from the ideal gas...
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 ...
