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]

i. Molar mass of glucose = 180 g/mol

ii. Amount of glucose = 0.5 mole

Explanation:

The volume of the glucose solution to be prepared = 500

Molarity of the glucose solution to be prepared = 1 M

i. Molar mass of glucose () = (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

2fe + 3h2so4 -> fe2(so4)3 + 3h2

it is necessary to balance equations in order to get the proper amount of reactants as well as products in order not to make a miscalculation.

you cannot change the subscripts as that would change the substance itself. for instance, diatomic elements such as h2 only have the subscript two when a gas. another example would be so4, if you were to change the subscript, the element would no longer be sulfate.

we change the coefficients instead as that only changes the number of molecules rather than the substance itself.

hope this !

12 is it do you think so
