Answer:
876.672 g
Step-by-step 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
