Question

mass of calcium that has the same number of atoms as in 16 g of CH4​

Answer 1

Answer:

16 g Methane = 6.023 x 10^23 molecules of Methane (CH4)

1 mole of CH4 = 5 x 6.023 x 10^23 atoms ( as CH4 has 5 atoms )

Total no. of atoms = 5 x Avogadro’s Number

Mass of 1 mole Mg = 24 g

Mass of (5 x Avogadro’s Number) Mg = 120 g

Ans : 120 g

Answer 2

Answer:

The relative atomic masses of all elements have been found with respect to an ... CH4 ⇒ 1 × 12 + 4 × 1 = 16 u ... Which has more number of atoms, 100 grams of sodium or 100 grams of
