Question

EXERCISES 6) How many moles are there in: Please show all work. No work, no points - include conversion factors and units) (a) 12 g of 'c (b) 120 g ofc (c) 2.5 g of CO2 (d) 4.3 x 10°C atoms

Answer 1

Answer will be as follows-

6 @ No. of moles - Amount of atom (8) atomne weight (g/mole) @ No. of moles = 128 . I mole in 128 of 1291 mole & No. of moles of 120gle = 120g = 10 mole 128 mole No of moles in 2.5g of co - Amount of ca 18) n0 6 0 ( 14 ) - 2.58 = 0.057 moles u s mole & , mole of a contains 6-02 2x13 atoms therefore no. of moles in 4.34100 calon = - 4.3410 6022X123 moles Anewer
