Answer:
One quart.
Explanation:
Let us consider the relation between all of the given units of volume and one litre.
a) one litre equals to 33.84 ounces
b) one litre equals to 2.11 pint
c) one litre equals to 0.95 quart
d) one litre equals to 4.54 gallons
Thus from above conversions it is clear that one litre is almost equal to or about 1 quart (0.95 approxes 1).
Molar mass Na = 23 g/mol
23 g ------------- 6.02 x 10²³ atoms
4.56 x 10⁻² g ----- ? atoms
atoms = 4.56 x 10⁻² x ( 6.02 x 10²³ ) / 23
atoms = 2.74 x 10²² / 23
= 1.19 x 10²¹ atoms
hope this helps!
<u>Answer:</u>
<em>To raise the pH of the solution to 3.10 we have to add 2.34 L of water.</em>
<u>Explanation:</u>
<em>Given that the pH of the solution of HCl in water is 2.5.</em> Here the solution’s pH is changing from 2.5 to 3.10 which means the acidic nature of the solution is decreasing here on dilution. ions contribute to a solution’s acidic nature and contribute to a solution’s basic nature.
The equation connecting the concentration of and pH of a solution is pH=

<em>When the pH is </em>
<em>On dilution the concentration of a solution decreases and volume increases.</em>
