Answer:
Solution given:
1 mole of KCl
22.4l
1 mole of KCl74.55g
we have
0.14 mole of KCl74.55*0.14=10.347g
74.55g of KCl22.4l
10.347 g of KCl22.4/74.55*10.347=3.11litre
volume of each solution contains 0.14 mol of KCl contain 3.11litre.
A halogen is example of
nonmetal. The answer is letter A. When compounds containing halogens they are
called salts thus the name “salt – former”. Halogen consists of Fluorine,
Chlorine, Bromine, Iodine, Astatine.

Answer:
Lithium is used in making electrochemical cells.
A mole is equal to 6.02x10^23, so one mole of H2O has 6.02x10^23 water molecules. To get how many of them are in 6 moles you need to multiple it by six:
(6.02x10^23)x6= 3.612x10^24
So, there’s 3.612x10^24 water molecules in 6 moles of water
