Question

A geochemist in the field takes a 25.0 mL sample of water from a rock pool lined with crystals of a certain mineral compound X. He notes the temperature of the pool, 26.° C, and caps the sample carefully. Back in the lab, the geochemist first dilutes the sample with distilled water to 350. mL. Then he filters it and evaporates all the water under vacuum. Crystals of X are left behind. The researcher washes, dries and weighs the crystals. They weigh 3.00 g.

1)Using only the information above, can you calculate the solubility of X in water at 26 degrees Celsius.? Yes or No

2) If yes than calculate the solubility of X. Round your answer to 3 significant digits

Answer 1

25 mL o Sample ,メ, Seldon was taken m a dosed galt^ present containen. So by Knewing the Amount in the Sample Soluuon we can e easily calculats he ram be几 Selubi lit in the unit So, the ans wen İS yes mi anaL Compound aften dry= 3.00 Amount Sample Solition wan taken. at the hal time 25 mL Compound X' wan pre water 久5 mL 25 ml Soludion Contain = 3.0。 ?m : 3 0 E 120 So, the Solabiu 0 12 120
