A. Protons and Neutrons will get u the atomic mass.
Answer:
319.3g Cu2S
Explanation:
There is 127.1 g Copper in 159.16g (molar mass) of Cu2S. Let x be Cu2S required. Then x * (127.1/159.16) = 255.0g. So x = 319.3g

The Question is incomplete here is the complete question " Suppose an iron atom in the oxidation state +3 formed a complex with three hydroxide anions and three water molecules. Write the chemical formula of this complex.
Answer:
{Fe(OH)3(H20)3}
Explanation:
Oxidation state is the electron gained or lost by and atom, So if iron is in +3 state in formula it must have lost three electron.
We know that OH posses the oxidation state of -1 and water have zero oxidation state. SO, Let's take iron equal to y and find its oxidation state in the formula
y + 3 ( - 1 ) + 3 ( 0 ) = 0
y - 3 + 0 = 0
y-3=0
y= + 3
Hence it's proved that iron has +3 oxygen state.
