Answer 1

Given that US concentration = 6 mg/L

Molecular weight of solute= 243 g/mol

One litre of drug consists of 6 mg of solute ie 0.006 g

Number of moles = 0.006 g/(243 g/mol)

= 2.469×10^-5 moles

10^-6 mole = 1 micromole (mcmol)

2.469 ×10^-5 moles = ? micromoles

= 2.469×10^-5/10^-6 micromoles(mcmol)

= 24.69 micromoles (mcmol)

Therefore 6 mg/L = 24.69 mcmol/L

B)

Given that US concentration = 38 mg/L

Molecular weight of solute= 114 g/mol

One litre of drug consists of 38 mg of solute ie 0.038 g

Number of moles = 0.038 g/(114 g/mol)

= 3.333×10^-4 moles

10^-6 mole = 1 micromole (mcmol)

3.333 ×10^-4 moles = ? micromoles

= 3.333×10^-4/10^-6 micromoles(mcmol)

= 333.3 micromoles (mcmol)

Therefore 38 mg/L = 333.3 mcmol/L

C)

Given that US Con. of 2 - 13 mE all Molecule weight - 160 Valency 13 mEq of z is prest in IL 13x10 equivaht of t n prent in IC. Equivalent Weight no of Equivalents - 7 ce Equivalent weight - 160 - ico - Valency Equivalent weight = GMW no of Equivalents & Equivaltweshta No. of mole & Molecules wesht No. of mol = no of equivalents - 13x10 moby. & 13 monol. = 13 mmol/e. : 13 m&k

Given Roncentration: 55 mEq/ Moleculer weight = 193 Valency & 2. 155 m g of a is prefut in il à 55x103 equivalent of z is prent in in.
