Question

How many grams of sodium will have the same number of atoms as 6g of magnesium

Answer 1

Answer:

Mole is the quantity in number having a mass equal to its atomic or molecular mass in grams

Magnesium Atomic no. 12

therefore, 1mol of MG=24g

now mol= given mass/molar mass

=6/24

=0.25 mol

now Sodium Atomic no. =11

therefore, 1mol of Na=23g

givemass= mol * molar mass

=o.25 * 23

=5.75 g
