Answer:
the density of a 40 gram object whose volume is 20 mL? Density = mass /volume = 40/20 = 2g/mL.
First calculate the Ar of the compound.. ( Ar of C6H12O6 is 180)
Then divide the At of the required element by 180 and multiply by 100...
so, for carbon 12 * 6 = 72 (THERE ARE 6 CARBON ATOM)
(72/180) * 100 =40%
ITS THE SAME FOR THE OTHER 2 ELEMENT
Answer:
Damian here!! :))
The carbon family consists of the elements carbon (C), silicon (Si), germanium (Ge), tin (Sn), lead (Pb), and flerovium (Fl). Atoms of elements in this group have four valence electrons. The carbon family is also known as the carbon group, group 14, or the tetrels. Elements in this family are of key importance for semiconductor technology.
