A geochemist in the field takes a small sample of the crystals of mineral compound X from a rock pool lined with more crystals of X. He notes the temperature of the pool, 26.° C, and caps the sample carefully. Back in the lab, the geochemist dissolves the crystals in 800. mL of distilled water. He then filters this solution and evaporates all the water under vacuum. Crystals of X are left behind. The researcher washes, dries and weighs the crystals. They weigh 0.032 kg. Using only the information'above, can you calculate O yes the solubility of X in water at 26.° C? O no If you said yes, calculate it. Be sure your answer has a unit symbol and 2 significant digits.

A geochemist in the field takes a small sample of the crystals of mineral compound X from a rock pool lined with more crystals of X. He notes the temperature of the pool, 24. C, and caps the sample carefully. Back in the lab, the geochemist dissolves the crystals in 3.00 L of distilled water. He then filters this solution and evaporates all the water under vacuum. Crystals of X are left behind. The researcher washes, dries and weighs the crystals. They weigh 45.0 g. Using only the information above, can you calculate yes the solubility of X in water at 24." C no If you said yes, calculate it. Be sure your answer has a unit symbol and 3 signiicant digits.

Suppose a group of volunteers is planning to build a park near a local lake. The lake is known to contain low levels of arsenic (As). Therefore, prior to starting construction, the group decides to measure the current level of arsenic in the lake. If a 11.7 cm³ sample of lake water is found to have 172.3 ng As, what is the concentration of arsenic in the sample in parts per billion (ppb), assuming that the density of the lake water is 1.00 g/cm³? concentration: ppb One of the volunteers suggests hiring an on-site water treatment company to remove the arsenic from the lake. The company claims their process takes 2.98 days to remove 31.30 kg of arsenic from a water source. Calculate the total mass, in kilograms, of arsenic in the lake that the company will have to remove if the total volume of water in the lake is 0.950 km³. total mass: kg
