Answer:
0.244 M.
Explanation:
From the question given above, the following data were obtained:
Molarity of stock solution (M₁) = 1 M
Volume of stock solution (V₁) = 0.305 L
Volume of diluted solution (V₂) = 1.25 L
Molarity of diluted solution (M₂) =?
The molarity of the diluted solution can be obtained by using the dilution formula as illustrated below:
M₁V₁ = M₂V₂
1 × 0.305 = M₂ × 1.25
0.305 = M₂ × 1.25
Divide both side by 1.25
M₂ = 0.305 / 1.25
M₂ = 0.244 M
Thus, the molarity of the diluted solution is 0.244 M
The atomic number increases moving left to right across a period and subsequently so does the effective nuclear charge. Therefore, moving left to right across a period the nucleus has a greater pull on the outer electrons and the atomic radii decreases.
I don’t know what the question is asking
Due to hydrogen bonding there is a formation of cage like structure called lattice in ice due to which <span> density of ice is less than that of water. Moreover, it is a known fact that density of water is maximum at 4°C.</span>
