To work out molarity, you need to know the total volume of solution as well as the number of moles of solute. Divide the number of moles of solute by the number of liters of solution. For example, if you have 3.4483 moles of table salt in 10 liters of water, work out 3.4483 ÷ ...
How many moles of ethanol (C2H5OH) would contain 25.0 grams of carbon? How many total moles of atoms are present in each of the following molar quantities? A) 4.97 moles N2O4 B) 4.75 moles HNO3 C) 0.229 mole C2H6O D) 8.90 moles (NH4)2S Find the molar mass of ethanol, C2H6O. A)...
One liter of an aqueous solution contains 6.02 * 10^21 H3O^+ ions. Therefore, what is H3O^+ ion concentration? How to find water of crystallization How to find the solubility product What is the [oh-] in a solution that has a [H3O+] = 2.0 ? 10-4 m?
The number 7 for a cholesterol level would not be a measurement in mg/dL, used in the U.S., but it may be in a measurement used in other countries. Canada, for example, uses millimoles per liter, or mmol/L, for cholesterol tests. 7 mmol/L is a very high LDL level....

like epilepsy, too. It also may help people with heart disease, certain brain diseases, and even acne, but there needs to be more research in those areas. Talk with your doctor first to find out if it’s safe for you to try a ketogenic diet, especially if you have type 1 diabetes....
mmol/L:millimoles per liter ng/mL:nanograms per milliliter pg (picograms):one-trillionth of a gram People worried about their health can also use the freeAda appto carry out a symptom assessment. Or find out more about how oursymptom checkerworks before you try it for yourself. ...
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/1 mol) = 6.48 mM NaOH. A one liter solution that contains 259 milligrams of NaOH is thus a 6.48 mM solution....
step 1: convert 5 ml to liters. 5 ml x 1 L / 1000 ml = 0.005 L (note ml cancel leaving us with L) step 2: write 0.30 M Pb2+in units of mol / L. 0.30 M = 0.30 moles Pb2+/ L step 3: find moles by using moles / L and L: 0.30 moles Pb2+/ L x 0.005 L = 0.001...
Calculate the molarityof a solution prepared by dissolving 23.7 grams of KMnO4into enough water to make 750 mL of solution. This example has neither the moles nor liters needed tofind molarity, so you must find the number ofmolesof thesolutefirst. ...
