Question
the mass percentage of chromium in steel is often much higher than that of manganese. If a steel sample of mass 0.800g has 34.1% Cr and is oxidized and diluted, calculate the concentration of Cr+3 in 150 mL of the diluted solution. the mass percentage of chromium in steel is often much higher than that of manganese. If a steel sample of mass 0.800g has 34.1% Cr and is oxidized and diluted, calculate the concentration of Cr+3 in 150 mL of the diluted solution. the mass percentage of chromium in steel is often much higher than that of manganese. If a steel sample of mass 0.800g has 34.1% Cr and is oxidized and diluted, calculate the concentration of Cr+3 in 150 mL of the diluted solution.Explanation / Answer
steel sample of mass = 0.800g
Chromium Percentgae = 34.1 %
Mass of Chromium = 34.1 x 0.8 / 100 = 0.2728 gm
Molar mass of Chromium = 51.996 gm/mol
Molar concentration of Cr3+ = 0.2728 x 1000 / 51.996 x 150 = 0.0349 M
