we have `(2.9g)/(0.05mol)` which means we have 2.9g in 0.05mol using ratio we can set up `(2.9g)/(0.05mol)=x/(1mol)`
solving for x we have `x=(2.9g*1mol)/(0.05mol)=58g` now got 58 and by looking at the periodic table we see that Nickel has molar mass of 58.69 which is the closest substance.
Therefore it is Ni
Explore and know. That is asked.
