Question

how much potassium chlorate would dissolve in 200 gram water at 20 degree Celsius​

Answer 1

The molar mass of pottasium chlorite is = (39.10)+ 35.45+(16×3) = 122.55 gm/mol

The molar mass of water is =16+(1×2)= 18gm/mol

the reaction between water and pottasium chlorite is

KClO3 + H2O ——› H2+ KClO4

so we can say that

122.55 gm pottasium chlorite dissolved in 18 gm of water

1 gm pottasium chlorite dissolved in 18/122.55 gm of water

in another way we can say that 18 gm of water is required to dissolve 122.55 gm of pottasium chlorite

1 gm of water is required to dissolve 122.5/18 gm of pottasium chlorite

so 200 gm of water is required to dissolve (200×122.5)/18 gm of pottasium chlorite = 1361.1 gm

And the whole process is happened at 20°C

Answer 2

Answer:

The molar mass of pottasium chlorite is = (39.10)+ 35.45+(16×3) = 122.55 gm/mol

The molar mass of water is =16+(1×2)= 18gm/mol

the reaction between water and potassium chlorite is

KClO3 + H2O ——› H2+ KClO4

so we can say that

122.55 gm potassium chlorite dissolved in 18 gm of water

1 gm potassium chlorite dissolved in 18/122.55 gm of water

in another way, we can say that 18 gm of water is required to dissolve 122.55 gm of potassium chlorite

1 gm of water is required to dissolve 122.5/18 gm of potassium chlorite

so 200 gm of water is required to dissolve (200×122.5)/18 gm of potassium chlorite = 1361.1 gm

And the whole process happens at 20°C
