How many grams of sodium wil have the same number of atoms as 6 grams of magnesium ("Given Na"=23u, Mg=24u)? |
|
Answer» Solution :Number of grams- atoms of MG = `("MASS of Mg in atoms")/("gram-atomic mass") = (6g)/(24 G) = (1)/(4)` `THEREFORE` gram - atoms of sodium should be `(1)/(4)` `because`1 gram - atom of sodium = 23 g `therefore (1)/(4)` gram-atom of sodium = `23 xx 1/4 g = 5.75 g` . |
