Question

if blood sugar level is 70 mg/dl.find its molarity.( sugar molecular mass = 342.3g/mol)​

Answer 1

Hello Mate!

1 kg = 1000 g.

So, 4 g of NaOH is dissolved in 1000 gof H2O.

Concentration of solution = wight of solute / weight if solution × 100%

Weight of solution = weight of solute + weight of solvent

= ( 4 + 1000 ) g

= 1004 g

So, concentration = 4/1004 × 100

= 0.4%

Hence concentration is 0.4%

Have great future ahead!
