SO2 is a polar molecule because Oxygen gains more electrons making one side more negative than the other.
1,516.31168 grams of Magnesium Hydroxide
Answer:
20.3 % NaCl
Explanation:
Given data:
Mass of solute = 45.09 g
Mass of solvent = 174.9 g
Mass percent of solution = ?
Solution:
Mass of solution = 45.09 g + 174.9 g
Mass of solution = 220 g
The solute in 220 g is 45.09 g
220 g = 2.22 × 45.09
In 100 g solution amount of solute:
45.09 g/2.22 = 20.3 g
Thus m/m% = 20.3 % NaCl
Step by Step Explanation
From the question,
the dimensions of the tank are;
L = 30 cm, way =0.075m and H = 15 cm
The density of water is given as

The unit of density given in the question means that the mass of the water is in grams and the volume should also be in

To find the volume of the water, we first convert the units of dimensions given in inches and metres to centimetres

This implies that ,

Also,

This implies that,

Now, the volume of water in the tank can hold, can be found from the relation;

This implies that,


Finally, we can calculate the mass of the water from the relation given;

This in implies that



Hence the fish tank can hold 0.857g water.
HCl is a strong acid therefore complete ionisation takes place
HCl ---> H⁺ + Cl⁻
1 mol of HCl dissociates to form 1 mol of H⁺
NaOH is a strong base therefore complete ionisation takes place
NaOH ---> Na⁺ + OH⁻
1 mol of NaOH dissociates to form 1 mol of OH⁻ ions
equal number of moles of HCl and NaOH will dissociate to give out an equal number of moles of H⁺ and OH⁻ ions.
H⁺ + OH⁻ --> H₂O
equal amount of H⁺ and OH⁻ together forms H₂O
since all the H⁺ and OH⁻ have now reacted to form water molecules the solution now becomes neutral as there are no excess H⁺ ions to make the solution acidic and no excess OH⁻ ions to make the solution basic.
Therefore the solution will be neutral.
