Answer:
1 mole ->111g CaCl2
∴ 222g CaCl2 is equivalent to 2 moles of CaCl2
since 1 formula unit CaCl2 gives 3 ions, therefore, 1 mol of CaCl2 will give 3 moles of ions
2 moles of CaCl2 would 3 x 2 = 6 moles
No. of ions = No. of moles of ions x Avogadro number
= 6 x 6.022 x 10^23
= 36.132×10^23
=3.6132×10^24 ions
Answer:
the silver compounds include:
silver chloride agcl ,
silver bromide agbr ,
and silver iodide agi.
49.1-45.5=3.6; you simply subtract the old density from the new density.
1 kg ----------- 2.20462 pounds
1.8 kg -------- ??
1.8 x 2.20462 / 1 => 3.96832 pounds
