PEBC – Calculations Questions With Complete Solutions
What is specific gravity of water? correct answer: 1 ml/1g
How many mg = 1 grain? correct answer: 65 mg = 1 grain
How do you calculate specific gravity? correct answer: weight
of liquid per x volume
divided by weight of water per same x volume
What is:
% v/v
% w/v
% w/w correct answer: % v/v = ml per 100 ml solvent
% w/v = g per 100 mg solvent
% w/w = g per 100 g diluent
1 mM (mililmol) = how many umols per mL? correct answer:
1mM = 1 mmol/L
= 1 umol/mL
equation for mEq? correct answer: mass of ion (g) * valence of
ion
divided by molecular mass (g/mol)
A hypotonic solution will cause body cells to ____ correct
answer: swell/burst (water moves from outside to inside
because too much water outside cells and too little solutes)
