Question

arrange in decreasing order by mass
(1) 10²³molecules of CO₂gass
(2) 0.1g atom of Ag
(3) 1g of C
(4) 0.1 mole of H₂SO₄
(5) 10²³atoms of Ca

Open in App

Solution

Mass of 6.022 $\times$ 10²³molecules of CO₂ gas = 18 g
Mass of 10²³molecules = $\frac{18}{6.022} = 2.989 g$

Mass of 1 g atom of Ag = 108 g
Mass of 0.1 g atom = $108 \times 0.1 = 10.8 g$

Mass of 1 mole of H₂SO₄ = 98 g
Mass of 0.1 mole = 9.8 g

Mass of 6.022 $\times$ 10²³molecules of Ca = 40 g
Mass of 10²³molecules = $\frac{40}{6.022} = 6.642 g$

Decreasing order of mass :

0.1 g atom of Ag > 0.1 mole of H₂SO₄> 10²³molecules of Ca > 10²³molecules of CO₂ gas > 1 g of C
2 > 4 > 5 > 1 > 3
