<span>Chromium is a transition metal and it has 24 electrons and here is the orbital diagram. If we're going to make this short hand and make the electron configurationfor this we would make this 1s2, 2s2, 2p6, 3s2, 3p6, 4s2, 3d4 okay from now on every time you see 3d4 you're going to change it, we do not like 3d4.</span>

Answer:
17.78g
Explanation:
m/M = C×V
m/101.102= 0.7× 0.25
m= 101.102×0.7×0.25= 17.78g
