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 ...
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 ...
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...
red blood cells (RBCs) and platelets.By measuring the volume of blood cells, the CBC allows a doctor to evaluate an individual’s overall health, as well as check for underlying conditions such as leukemia andanemia.3
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....
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 ...
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 ÷ ...
I'll do it in individual steps first, and then show you how to do it all in one calculation: 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 Pb...
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 f
How many milliliters in a liter? Person A takes 8 hours to get to a destination driving 77 mph non-stop. Person B takes 11.5 hours to drive the same distance stopping twice for 15 minutes each time. How many mph was Person B driving?
