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 do you convert 1.25 kilograms to grams?
To convert kilograms to grams, you need to multiply by 1000 since there are 1000 grams in a kilogram. Therefore, to convert 1.25 kilograms to grams, you would multiply 1.25 by 1000, resulting in 1250 grams.
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.
How do you convert 90 grams of NaCl to moles?
The answer is 1,54 moles.
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.
How many grams in 1.6 mol NaCl?
To convert moles to grams, you need to use the molar mass of NaCl. The molar mass of NaCl is approximately 58.44 g/mol. Therefore, 1.6 mol of NaCl would be equal to 1.6 mol * 58.44 g/mol = 93.504 grams of NaCl.
How many grams are in 6.5 moles of NaCl?
To convert moles to grams, use the molar mass of NaCl. The molar mass of NaCl is approximately 58.44 g/mol. Therefore, 6.5 moles of NaCl would be 6.5 moles x 58.44 g/mol = 379.26 grams of NaCl.
How do I convert 38 grams of NaCl to moles and formula units?
To convert 38 grams of NaCl to moles, you first find the molar mass of NaCl (58.44 g/mol) and then divide the mass by the molar mass to get moles (38g / 58.44 g/mol = 0.651 moles). To convert moles to formula units, you multiply the number of moles by Avogadro's number (6.022 x 10^23 formula units/mol), giving you 3.92 x 10^23 formula units.
How many mole are in 11.2 grams of nacl?
To convert grams to moles, you need to divide the given mass by the molar mass of the substance. The molar mass of NaCl (sodium chloride) is 58.44 g/mol. Therefore, 11.2 grams of NaCl would be equal to 0.191 moles.
How many grams are in 0.160 mole of sodium chloride?
To convert moles to grams, you need to multiply the number of moles by the molar mass of the substance. Sodium chloride has a molar mass of 58.44 g/mol. 0.160 mole x 58.44 g/mol = 9.35 grams
How many grams of NaCl are in 200mg of a 10 percent salt solution?
There is 20mg of NaCl in 200mg of a 10% salt solution. To convert mg to g, divide by 1000: 20mg = 0.02g of NaCl.
How many grams of NaCl are in 225 grams of an 18 percent NaCl solution?
The answer is 8 g NaCl.
How do you convert 200mL to moles?
To convert 200mL to moles, you need to know the substance's molar mass. Once you have the molar mass, you can use the formula moles = volume (in liters) / molar volume to determine the number of moles. Remember to convert milliliters to liters by dividing by 1000.
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?
To calculate the molarity of the solution, we first need to determine the number of moles of NaCl in 400 mg. The molar mass of NaCl is approximately 58.44 g/mol. Converting 400 mg to grams gives us 0.4 g. Dividing this by the molar mass gives us approximately 0.0068 moles of NaCl. Since the volume is 100 mL or 0.1 L, the molarity is calculated as moles divided by liters, giving us approximately 0.068 M.
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 ======================
