Question

In laboratory experiment, a NOVDEC Student was

required to prepare 500 cm3 of Im Solution of
glucose (c6, H12,06) Determine the
i Molar
Mass
ii) Amount of ghicoseB. In in moles in the Solrition
[ C= 12, H = 10, 0=16]​

Answer 1

i. Molar mass of glucose = 180 g/mol

ii. Amount of glucose = 0.5 mole

Step-by-step explanation:

The volume of the glucose solution to be prepared = 500
`cm^3`

Molarity of the glucose solution to be prepared = 1 M

i. Molar mass of glucose (
`C_1_2H_6O_6`) = (6 × 12) + (12 × 1) + (6 × 16) = 180 g/mol

ii. mole = molarity x volume. Hence;

amount (in moles) of the glucose solution to be prepared

= 1 x 500/1000 = 0.5 mole
