How many grams are in 11.9 moles of chromium?

Answers

Explanation:It is known that one mole of chromium or molar mass of chromium is 51.99 g/mol.It is given that number of moles is 11.9 moles.Therefore, calculate the mass of chromium in grams as follows.      No. of moles = [tex]\frac{mass in grams}{Molar mass}[/tex]     mass in grams = No. of moles × Molar mass                              = 11.9 moles × 51.99 g/mol                              = 618.68 gThus, we can conclude that there are 618.68 g in 11.9 moles of chromium.

1mole        ----- 52g Cr11,9moles  --- xx = 11,9*52/1 = 618,8[g]
