Calculate the number of grams of aluminum chloride and water formed when 0.500 g of aluminum hydroxide react with stomach acid.

Answer : The mass of and produced will be, 0.852 and 0.346 grams respectively.

Explanation : Given,

Mass of = 0.500 g

Molar mass of = 78 g/mole

Molar mass of = 133 g/mole

Molar mass of = 18 g/mole

First we have to calculate the moles of .

Now we have to calculate the moles of and .

The balanced chemical reaction is,

From the balanced reaction we conclude that

As, 1 mole of react to give 1 mole of

So, 0.00641 mole of react to give 0.00641 mole of

And,

As, 1 mole of react to give 3 mole of

So, 0.00641 mole of react to give mole of

Now we have to calculate the mass of and .

and,

Therefore, the mass of and produced will be, 0.852 and 0.346 grams respectively.

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

the answer is a. co2, this would be colder than the : )
