Answer:

Explanation:

Cr₂O₃ ( chromium oxide )

Mass of Cr₂O₃⁻ = 2 x 52 + 3 x 16 = 104 + 48 = 152

152 gram chromium oxide contains 104 grams chromium

152 tonnes chromium oxide contains 104 tonnes chromium

5 tonnes chromium oxide contains 104 x 5 / 152 tonnes chromium

mass of chromium required =  104 x 5 / 152 tonnes

= 3.42 tonnes .
