Atomic mass iron ( Fe ) = 55.84 a.m.u
55.84 g ------------ 6.02x10²³ atoms
24.0 g ------------- ??
24.0 x ( 6.02x10²³) / 55.84
=> 2.58x10²³ atoms
No of moles= 88/44 =2
therefore no. of molecules =
therefore no.of molecules= 12.046*10^23
Lipids are in a class called fat or lipid solvents.
Pressure does not affect the voltage produced in a voltaic cell.
#1
- See H and C have shared their electrons so it's Covalent bonding
#2
Yes here we can see the dots and crosses clearly.
#3
It's Methane or CH_4
#4
There is no double bond
