Question

Determine the mass in grams of 7.20 mol of antimony(molar mass =121.76g​

Answer 1

Answer:

876.672 g

Explanation:

Data given:

moles of antimony (Sb) =7.20  mol

Molar mass of Sb= 121.76 g

Mass in grams of Sb

Formula to be used

                      no. of moles = mass in grams / molar mass

For antimony (Sb) we can write as

        no. of moles of Sb = mass in grams of Sb / molar mass of Sb

Rearrange above equation

    mass in grams of Sb = no. of moles of Sb x molar mass of Sb . . . . . . .(1)

Put values in above formula (1)

 mass in grams of Sb = 7.20 mol x 121.76 g/mol

mass in grams of Sb = 876.672 g
