If 250 g of calcium chlorate decomposes into calcium chloride and oxygen, what mass of oxygen would be produced?

→ +

115.97 grams

Explanation:

The reaction ensuing is expressed as:

-The molar mass of is given as

#Calculate the moles of in the reaction:

#The ratio of calcium chlorate to oxygen is 1:3,

#Given the molar mass of oxygen per mole is 32 g, it's weight in the reaction is calculated as:

Hence, the mass of oxygen produced is 115.97 grams

"it was found that some people who were taking the drug l-dopa to raise their levels of dopamine were developing schizophrenic-like symptoms supporting research a strength of the dopamine hypothesis is that there are many studies which have shown support for the neurochemical explanation."
