Question

2 moles of pure gypsum is heated to convert
it completely to plaster of paris. What is the
number of moles of steam evolved in the
process.​

Answer 1

half moles of steam evolved in the process of plaster of paris formation

Answer 2

Half moles of steam is evolved:

Explanation:

The process involves half a mole of steam.

• To begin, let's define the terms: gypsum is a naturally occurring mineral found in nature, and plaster of Paris is a white powder sold in bags for use in casting.

• POP is made by crushing gypsum into finer stones and then heating it to remove some of the water. The formula would be as follows:

• CaSO₄. 2 H₂O (Gypsum) converted into CaSO₄. 1/2 H₂O (POP)

• This is reversible: add water to the powder POP and it turns into a hard 'stone' Gypsum in minutes;
• the recipe can be reversed; this is indefinitely recyclable.
