Question

arrange the following in order of their increasing masses in grams (1) one atom of silver (2) 0.1 mole of H2SO4(3) 1023 atoms of carbon (4) 1 mole of Oxygen molecules

Answer 1

Let us calculate masses in each case

1) Mass of silver = 0.1g

2) Number of moles = given mass / molecular weight

0.1 = Given mass/98

Mass of H2SO4 = 0.1 X 98 = 9.8g

3) 1 mole Ca has 6.022 X 1023 atoms

1 mole of Ca = Its atomic weight = 40g

Mass of 6.022 X 1023 atoms = 40g

Then mass of 1023 atoms of Ca = 1023 X 40 / 6.022 X 1023 = 6.4g

Increasing order according to their masses: 0.1g of Ag < 1023 atoms of Ca < 0.1 mole of H2SO4 

hope it helps u!!!!
