A geochemist in the field takes a 13.0 mL sample of water from a rock pool lined with crystals of a certain mineral compound X. He notes the temperature of the pool, 16.° C, and caps the sample carefully. Back in the lab, the geochemist filters the sample and then evaporates all the water under vacuum. Crystals of X are left behind. The researcher washes, dries and weighs the crystals. They weigh 0.143 g

Required:
Using only the information above, can you calculate the solubility of X in water at 15°C ? If you said yes, calculate it.

Respuesta :

Answer:

The answer is YES

The value is [tex]S = 110 \ g/L[/tex]

Explanation:

From the question we are told that

The volume of the sample taken is v = 13.0 mL

The temperature is [tex]T = 16^oC[/tex]

The mass of the sample is [tex]m = 0.143 g[/tex]

Generally the solubility of the substance X is mathematically represented as

[tex]S = \frac{m}{V}[/tex]

=>        [tex]S =  \frac{0.143  }{13.0}[/tex]

=>         [tex]S = 0.011 \  g/mL[/tex]

=>         [tex]S = 110 \  g/L[/tex]
