Answer:
Determine the volume of occupied by 2.34 grams of carbon dioxide gas at STP?
It's simple problem of ideal gas equation.
Answer:
%age of Carbon is 42.10 %.
Explanation:
In order to find the %age of elements present in a molecule we will use following formula,
%age of Element = (Mass of Element / Mass of Molecule) × 100
The molecular mass of Sucrose is.
= (12)12 + (1)22 + (16)11
Where;
12 = Atomic mass of Carbon
1 = Atomic Mass of Hydrogen
16 = Atomic Mass of Oxygen
= 144 + 22 + 176
= 342 g/mol
%age of C;
= (144 / 342) ×100 = 42.10 %
%age of H;
= (22 / 342) ×100 = 06.42 %
%age of O;
= (176 / 342) ×100 = 51.46 %
