Answer:
the color of the litmus paper will turn into blue color because sodium carbonate is basic in nature
Lowered cos the higher the ph the lower the hydrogen ions
As the atomic mass of iron is 55.847u
We say that it is the mass of one mole of iron.
By formula it can be find by
No.of mole=mass in g/molar mass
Mass in gram = no.of mole x molar mass
No.of mole =1
Molar mass = 55.847g
Mass in gram = 1x55.847
= 55.847g of Fe
