What is the term for the concentration expression that relates the moles of solute dissolved in each liter of solution?
Molarity, abbrev. M, units: mol/L, mmol/ml
How many mls of a 100mmolar glycine solution contains .005 moles of glycine?
Some conversion required. (mmolar into mol, or moles into mmol ) Molarity = moles of solute/Liters of solution 100 millimolar = 0.1 M glycine Molarity = moles of solute/Liters of solution manipulate algebraically Liters of solution = moles of solute/Molarity 0.005 mole glycine/0.1 M glycine = 0.05 Liters ( 1000 ml/1 L) = 50 milliliters of solution --------------------------------
If 25.5mg of oxalic acid dihydrate are dissolved in 1.00 ml of solution what is the molarity of the resulting solution?
0.063 g of oxalic acid * (1 mol H2C204*2H2O / 126.07 g) = 0.0004997 mol H2C2O4*2H2O 0.0004997 mol H2C204 / 0.250 L = 0.001999 M of H2C2O4
How many grams are equal to 450 milligrams?
Molarity = moles of solute/Liters of solution ( 450 ml = 0.450 liters) 5M C6H12O6 = moles C6H12O6/0.450 liters = 2.25 moles C6H12O6 (180.156 grams/1 mole C6H12O6) = 405.351 grams of glucose ( you do significant figures )
What is the suger range in human body?
The body maintains the blood glucose level between about 3.6 and 5.8 mM (mmol/L, i.e., millimoles/liter), or 64.8 and 104.4 mg/dL. normal blood glucose level in humans is about 4 mM (4 mmol/L or 72 mg/dL, i.e. ~issa~

How do you convert mmol to milliters?
1 mol = 103 mmol Conversely, 1 mmol = 10-3 mol For example: 25 mol x 103 mmol/1 mol = 25000 mmol and, 3.2 mmol x 10-3 mol/1 mmol = 0.0032 mol
A 25.0 ml of 0.106M KIO3 is put into a 250 ml flask and is titrated to a stoichiometric point with 16.25 ml of a sodium thiosulfate solutiom What Molarity of sodium thiosulfate?
Jodate: IO3- + 6e- + 6H+ --> I- + 3H2Oequivalency to:Thio: 6S2O32- --> 3S4O62- + 6e-25.0 ml * 0.106 mmol/ml (KIO3) = 2.65 mmol KIO3 reacting (1:6) with Thio: 6*2.65 = 15.9 mmol sodium thiosulfate. This is in 16.25 ml, so the molarity is 15.9 mmol / 16.25 == 0.978 M thiosulfate
How much sodium bicarbonate would be required to prepare 500ml of a 100mM solution?
500 mL * 100(mMol/mL) = 50 mMol NaHCO3 , hence50 mMol NaHCO3 = 50(mMol) * 84(mg/mMol) = 4200 mg = 4.2 g NaHCO3 in 500 mL
If 25.5mg of oxalic acid dihydrate are dissolved in 1.00 ml of solution what is the molarity of the resulting solution?
0.063 g of oxalic acid * (1 mol H2C204*2H2O / 126.07 g) = 0.0004997 mol H2C2O4*2H2O 0.0004997 mol H2C204 / 0.250 L = 0.001999 M of H2C2O4
What is the normal blood glucose levels for a healthy person?
The average blood glucose level for an adult male is around 4 mmol/L. Levels up to 5.9 mmol/L is considered normal and the level should be taken after fasting. However, if the test was taken after a meal, the level may be slightly higher at 7.8 mmol/L.
What is glucose mmol l?
The abbreviation "mmol/L." is a mole measurement of plasma glucose in a volume of blood. It stands for millimoles per liter in a sample of blood. Another common measurement of plasma glucose is taken weight as milligrams per deciliter or "mg/dL." Both mesurements are commonly called "blood sugar levels."
How many grams are equal to 450 milligrams?
Molarity = moles of solute/Liters of solution ( 450 ml = 0.450 liters) 5M C6H12O6 = moles C6H12O6/0.450 liters = 2.25 moles C6H12O6 (180.156 grams/1 mole C6H12O6) = 405.351 grams of glucose ( you do significant figures )
Is a glucose reading of 117 of concern?
No. Normal is between 80 mg/dl and 150 mg/dl. This is slightly over 4 mmol/l to 8.33 mmol/l. Many doctors look for values from 100 to 125 mg/dL (5.6 to 6.9 mmol/L)
How high a glucose level will cause a diabetic shock?
Diabetic shock normally refers to low glucose levels. Anything below 70 mg/dl (3.9 mmol/l) is low, but for some diabetics 80 mg/dl to 120 mg/dl (4.4 mmol/l to 6.7 mmol/l) can be a problem. High glucose doesn't generally lead to "shock," but long-term high glucose levels can damage the kidneys, nerves (especially in the feet and legs), the heart, and the retina.

What is the normal blood glucose levels?
Blood glucose also called blood sugar can be measured before and 2 hours after meals.. Normal blood sugar is from 4.0 to 5.9 mmol/L 2 hours after a meal under 7.8 mmol/L. For Type 2 Diabetes its 4 to 7 mmol/L 2 hours after a meal under 8.5. If you do have more questions ask your Doctor.
