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
<u>Answer:</u>
<em>0.264 g of can be formed from 288 mg of </em>
<u>Explanation:</u>
The balanced chemical equation is
The conversions are
Mass in mg is converted to mass in g
Mass in g is converted to moles by dividing with molar mass
Moles is converted to moles by using the mole ratio of is 9 : 6
Moles is converted to mass by multiplying with molar mass
mass in mg > mass in g >moles > moles > mass
=0.264g (Answer)
A) solid
b)liquid
c)liquid
d)gas
Anything can be broken down, as long as it is not as small as an atom
