a solution has 23.22% mass/concentration of a particular solvent what is the mass of solute dissolved in 2.5 liter of solvent?
aleksandrvk [35]
Let the mass of the solute be x

So, the equation would be
x/2.5+x ×100 = 23.22
x/2.5+x = 23.22/100
100x = 58.05 + 23.22x
100x - 23.22x = 58.05
76.78x = 58.05
x =0.756 ≈ 0.76 litres

Using your periodic table, identify element X based on its average atomic mass.
77julia77 [94]

The relative atomic mass of the element is 15.99 and the element is oxygen.

<h3>What is the relative atomic mass of the element?</h3>

Let us note that owing to the fact that elements often have isotopes, the relative atomic mass is not always a whole number. Now we have tp obtain the relative atomic mas from the atomic masses of the elements.

Thus;

X = (15.99 * 0.99762) + (16.999 * 0.00038) + (17.999 * 0.002)

X = 15.95 + 0.0065 + 0.036

X= 15.99

Thus the relative atomic mass of the element is 15.99 and the element is oxygen.
