prozac C17H18F3NO is a widely used antidepresent that inhibits the uptake of sertonin by the brain. how many molecules are in 3 grams of prozac?

Answer 1

Molar mass prozac

C17H18F3NO = 309.33 g/mol

1 mol -------------- 309.33 g
x mol -------------- 3 g

x = 3 / 309.33

x = 0.00969 mol

1 mol ------------- 6.02x10²³ molecules
0.00969 --------- y molecules

y = 0.00969 * 6.10x10²³

y = 5.83x10^21 molecules

hope this helps!.
