The moles of a substance is equal to the ratio of the mass of the substance to its molar mass. For example, the number of moles of 10.0 g of NaOH can be determined as follows: {eq}\rm Moles = \dfrac{mass}{molar\, mass} \\ Molar\, mass = 40.0\ g/mol\\ Moles = \dfrac{10.0...

For example, if you have 3.4483 moles of table salt in 10 liters of water, work out 3.4483 ÷ 100 = 0.0345. The molarity is 0.0345 M.Cite This Article MLA Gillespie, Claire. "How To Determine Moles Of Solute" sciencing.com, https://www.sciencing.com/determine-moles-solute-8483482/. ...
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 ...
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. ...
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...

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. What are ...
First, begin by converting millimolar to molar: (10 mmol MgCl2/1 L)x(1 mol/1000 mmol) = 0.010 mol MgCl2/1 L. Next, you can use the molar mass to find how many grams of MgCl2 there are in 0.010 moles or MgCl2: (0.010 mol MgCl2/1 L)x(96.211 g MgCl2/1 mol MgCl2) = 0.962 g...
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. ...
