Question

What is the concentration of sugar (C,H,,,,) in mol L- if its 20 g are dissolved in
enough water to make a final volume up to 2L?​

Answer 1

Answer:

Explanation:

CHEMICAL FORMULA OF SUGAR=C12H22O11

MOLAR MASS OF SUGAR=12*12+22*1+11*16=342

MASS OF SUGAR ADDED=20g

NUMBER OF MOLES=MASS OF SUGAR ADDED /MOLAR MASS

=20/342=0.0584

MOLARITY=NUMBER OF MOLES OF SOLUTE/VOLUME OF SOLUTION IN LITRE=0.0584/2=0.0292M
