Question

Number of chloride ions present in 0.1mol cacl2

Answer 1

Answer:

1.2x10²³

Explanation:

moles of cl atom=0.1X2=0.2

NO. of cl ion=0.2x6.02x10²³

=1.2x10²³

Answer 2

"Answer:

1.2044 x 10^23 ions of chloride

Explanation:

1 mole of CaCl2 = 111 g

1 mole of CaCl2 contains 2 moles of Cl

0.1 mole of CaCl2 contains ? moles of Cl

? = 0.1 x 2 = 0.2 moles of Cl

1 mole = 6.022 x 10^23 ions

0.2 moles = ? ions

0.2 x 6.022 x 10^23

1.2044 x 10^23 ions of chloride
