Answer: 0.6906 g/cm^3

Explanation:

$$We know that density $=\frac{\text { mass }}{\text { volume }}$\\\\Volume of the cube, $V=l^{3}=(1.500 \mathrm{~cm})=3.375 \mathrm{~cm}^{3}$\\\\Density of the cube $=\frac{2.331 \mathrm{~g}}{3.375 \mathrm{~cm}^{3}}=0.6906 \mathrm{~g} / \mathrm{cm}^{3}$\\\\ \therefore{\text{Density of the cube,} \ $\rho_{\text {cube }}{=0.6906 \mathrm{~g} / \mathrm{cm}^{3}$

What is the pH of a 0.28 M solution of ascorbic acid
Nady [450]

Hey there!

Values Ka1 and Ka2 :

Ka1 => 8.0*10⁻⁵

Ka2 => 1.6*10⁻¹²

H2A + H2O -------> H3O⁺  + HA⁻

 Ka2 is very less so I am not considering that dissociation.

Now Ka = 8.0*10⁻⁵ = [H3O⁺] [HA⁻] / [H2A]

lets concentration of H3O⁺  = X then above equation will be

8.0*10−5 = [x] [x] / [0.28 -x

8.0*10−5 = x² /  [0.28 -x ]

x² + 8.0*10⁻⁵x  - 2.24 * 10⁻⁵

solve the quardratic equation

X =0.004693 M

pH = -log[H⁺]

pH = - log [ 0.004693 ]

pH = 2.3285

Hope that helps!
