Question

how many gram magnesium will have the same number of atom as 6g of carbon

Answer 1

Molar mass of carbon = 12 g/mole
Number of moles of carbon in 6 g = 6/12 = 0.5
Number of atoms in 1 mole of carbon = 6.02 x 1023
Number of atoms in 0.5 moles of carbon = 6.02 x 1023 x 0.5 = 3.01 x 1023
 
Now, mass of 6.02 x 1023 atoms of magnesium = 24 g
Mass of 3.01 x 1023 atoms of magnesium = (24/6.02 x 1023 ) x 3.01 x 1023
   = 12 g

Answer 2

Answer:

12 gram

Explanation:

1mole of carbon=12gram

12gram of carbon=1mole

6gram of carbon=0.5moles

0.5moles of magnesium=24gram

1mole of magnesium =24gram

0.5moles of magnesium =24×0.5=12gram
