Both 5% and 25% albumin USP have a calculated osmolarity near 300 mOsm/L. How do I calculate that? The package inserts for both strengths state they contain 145 mEq/L of sodium. Since for each cation there must be an anion, that puts the osmolarity at 290 mOsm/L. The contribution of albumin to the total osmolarity is minimal. One mole of albumin is about 70,000 grams, so a 50 mL vial of albumin 25% (12.5 grams albumin) would only contribute about 3.57 mOsm/L to the total osmolarity. Hospital pharmacists are warned not to dilute 25% albumin with water to make 5% albumin because the osmolarity of the final product is too low. - Marty, R.Ph.
What else can I help you with?
How many moles in human albumin?
The number of moles in human albumin depends on the specific mass of the albumin sample being considered. Human serum albumin has a molecular weight of approximately 66,500 g/mol. To calculate the moles, you would divide the mass of the albumin sample in grams by its molecular weight (66.5 g/mol). For example, if you have 100 grams of albumin, you would have about 1.5 moles (100 g / 66.5 g/mol).
What is the molecular formula of the principal molecular or ionic species present in glucose?
It is a molecular species with the formula C6H12O6
What is the molecular formula of a compound that has a molecular mass of 54 and the empirical formula C2H3?
The empirical formula C2H3 has a molecular mass of 27 (C: 12, H: 1). To determine the molecular formula with a molecular mass of 54, the molecular formula would simply be double the empirical formula, so the molecular formula would be C4H6.
Is CCI4 a molecular formula or formula unit?
CCl4 is molecular formula.
Vitamin c has an emperical formula of c3h4o3 and a molecular mass of 176what is the molecular formula of vitamin c?
To find the molecular formula from the empirical formula, we need to know the molar mass of the empirical formula. In this case, the empirical formula's molar mass is 88. To find the molecular formula, we divide the given molecular mass (176) by the empirical formula's molar mass (88) to get 2. This means the molecular formula of Vitamin C is twice the empirical formula, so the molecular formula is C6H8O6.

Will glucose and albumin diffuse through 200 MWCO?
Glucose (180 g/mol) will diffuse through a 200 MWCO membrane, as its molecular weight is lower than the cutoff. Albumin (molecular weight around 66 kDa or 66,000 g/mol) will not diffuse through a 200 MWCO membrane, as its molecular weight exceeds the cutoff.
