How many moles of potassium oxide (k2o) will be formed when 1.52 moles of potassium reacts with oxygen according to the following reaction : 4 k + o2 = k2o

The moles of potassium oxide produced by the 1.52 moles of potassium ions are 0.76 moles.

The reaction of potassium and oxide will be given as:

From the reaction, 4 moles of potassium will give 2 moles of Potassium oxide.

So, 1.52 moles of potassium gives:

moles

= 1.52 0.5 moles

= 0.76 moles.

The moles of potassium oxide produced by the 1.52 moles of potassium ions are 0.76 moles.

1. 1 mole of anything contains 6.022x10^23 pieces  

d  

2. a  

3. c, number  

5. 1.24x10^24atoms / 6.022x10^23atoms/mole = 2moles h2 atoms  

6. fe2br3 mass = 2moles x mass fe + 3 moles x mass br  

molar mass = grams / number of moles = g/mole  

to find moles = g / molar mass  

to find mass = g = molar mass / moles
