How do you convert mgdl to mmoll?
Divide by 18 and that should do it.Thats's OK if you are asking about blood glucose. The factor changes if you are talking about cholesterol or any other blood measurement.
How many grams of NaCl would you use to make 100ml of a 4M solution?
The Molecular Weight of NaCl = 58.5 So to make 1L of 4M NaCl solution you need 4*58.5=234g of NaCl So to make 100mL of the above solution you need 23.4 grams of NaCl
How can you add 1300 kg plus 33.00g plus 0.28mg as gram in chemistry?
You convert everything to grams, then you add. * To convert kg to grams, you multiply by 1000. * To convert mg to grams, you divide by 1000.
How to convert ph to ppm?
Write an equation representing the ppm concentration: ppm = mass solute (mg) ÷ volume solution (L) Extract the data from the question: mass solute (NaCl) = 0.0045 g. ... Convert the mass in grams to a mass in milligrams: mass NaCl = 0.0045 g = 0.0045 g × 1000 mg/g = 4.5 mg.
Convert 3.5 grams to milligrams?
3.5 grams = 3, 500 milligrams
How do you convert 90 grams of NaCl to moles?
The answer is 1,54 moles.
How do I convert 38 grams of NaCl to moles and formula units?
For this you need the atomic (molecular) mass of NaCl. Take the number of grams and divide it by the atomic mass. Multiply by one mole for units to cancel. NaCl=58.5 grams38.0 grams NaCl / (58.5 grams) = .650 moles NaCl
How do you convert 200mL to moles?
1 mole of NaCl is 58.44 g 200 g NaCl * (1 mol NaCl/58.44 g NaCl) = 3.422 mol NaCl There are about 3.4 moles in 200 grams of NaCl.
Explain the following weight approximately 5 grams of NaCl to the nearest milligram?
5 grams of NaCl, or table salt, is equal to 5,000 milligrams. to convert grams to milligrams you simply multiply by 1,000.
The sterile solution used to rinse contact lenses can be made by dissolving 400 mg of NaCl in sterile water and diluting to 100 mL. what is the molarity of this solution?
First, find the moles of NaCl. Because you have 400 milligrams of NaCl convert to grams by dividing 1000mg. 400mg/1000mg = 0.400 grams of NaCl. Now we need to convert to moles. For every mole of NaCl there is 58.44 grams. (22.99g Na + 35.45 g Cl) so using stoichiometry (grams cancel) I get .0068 moles of NaCl. Conver 100 mL to L by dividing by 1000mL. Therefore there is .001 L in the solution. Molarity is moles per Liter. So 0.0068 mols of NaCl / 0.001 L = 6.84 M
How many grams of NaCl are in 225 grams of an 18 percent NaCl solution?
The answer is 8 g NaCl.
How many grams of NaCL are produced when 80.0 grams of O2 are produced?
96.75 grams of NaCl
How may grams are in 1.946 moles of NaCl?
1.946 moles NaCl (58.44 grams/1 mole NaCl) = 113.7 grams sodium chloride ======================
How many moles are in 20.0 grams of NaCl?
For this you need the atomic (molecular) mass of NaCl. Take the number of grams and divide it by the atomic mass. Multiply by one mole for units to cancel. NaCl=58.5 grams20.0 grams NaCl / (58.5 grams) =.342 moles NaCl
What is the percent of NaCl if 2.55 grams of NaCl is dissolved in 8.85 grams of H2O?
The answer is 28,81 %.
How many grams of NaCl are in 1.92 moles of NaCl?
Every mol of NaCl contains a mol of Na, weighting 23 grams, and a mol of Cl, weighing 35.5 grams. So, every mol of NaCl weights 58,5 (=23+35.5) grams. Therefore, 145 moles of NaCl weights 8482.5 grams.
How do you CONVERT 0.1m NaCl to 1m NaCl?
Increase the concentration of NaCl evaporating the water.
