Answer:
52.17%
Explanation:
COCl2.6H20
C=12,O=16,Cl=35.5,H=1
Relative molecular mass of COCl2.6H2O= 12+16+71+6(2+16) = 99 + 108= 207g
Relative molecular mass of 6H2O = 108g
Percentage of water = (108/207 )*100
= 52.17%
Hi there! :)
Both are compounds.
contains 1 carbon (C) atom and 2 oxygen (O) atoms.
It contains two different elements, so it is a COMPOUND.
is an IONIC compound with elements Sodium (Na) and Oxygen (O), which are different elements. Therefore, it is also a COMPOUND.
You should use Avogadro’s number for the conversion, because Avogadro’s Law states that there are 6.02 x 10^23 atoms per 1 mol of that substance.
The correct chemical formulae is CsBr
