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.
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
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.
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.
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.
