How many miles are there in 20g of KClO3 (k=39 Cl=35.5 O=16)​
SashulF [63]
<h3>Answer:</h3>

0.144 moles

<h3>Explanation:</h3>
  • The relationship between mass of a compound, number of moles and molar mass of the compound is given by;
  • Number of moles = Mass ÷ Molar mass
  • Molar mass is equivalent to the relative formula mass of the compound that is calculated the atomic masses of the elements making the compound.

In this case;

Our compound, KClO3 will have a molar mass of;

= 39 + 35.5 + 4(16)

= 138.5 g/mol

Mass of KClO3 is 20 g

Therefore;

Number of moles = 20 g ÷ 138.5 g/mol

                            = 0.144 moles

Thus, the number of moles in 20 g of KClO3 is 0.144 moles

b. Conducts electricity when dissolved in water

Explanation:

Iron(II) chloride, is the chemical compound with formula FeCl2.

It is a solid with a high melting point of about 677 degree Celsius or 950 K when in anhydrous form but have lower melting point in hydrated form.

The compound is often off-white. FeCl2 crystallizes from water as the greenish tetrahydrate, which is the form that is most commonly encountered in the laboratory.

There is also a dihydrate. The compound is highly soluble in water, giving pale green solutions.
