<span>Sediments
Sediments are solid materials that were broken down by the process of erosion, weather and transported by the water, wind or glaciers and then deposited in a new location. Sediment can consist of minerals and rocks and can be as small as a grain of sand or as large as a boulder.</span>
Answer : The volume of
is 14.784 L.
Solution : Given,
Mass of Aluminium = 6 g
Molar mass of Aluminium = 27 g/mole
First we have to calculate the moles of aluminium.
Moles of Al = 
The given balanced reaction is,

From the reaction, we conclude that
2 moles of Al react with the 6 moles of 
0.22 moles of Al react with
of 
At STP, 1 mole contains 22.4 L volume
As, 1 mole of
contains 22.4 L volume of 
0.66 moles of
contains
volume of 
Therefore, the volume of
is 14.784 L.
Moles=mass/molar mass of water. the molar mass of water is found to be 18g which is calculated adding the molar mass of hydrogen plus that of oxygen that is(2x 16)+(1 x2)=18g/mol
convert Kg to grams that is 1.8kg x 1000=1800g
moles is therefore 1800g /18g/mol=100 mol
35g Mg x 1mol / 24g = 840 mol
