1) A solution is made by mixing 134.g of acetic
acid HCH3CO2 and 38.g of acetone
CH32CO Calculate the mole fraction of acetic acid in this
solution. Round your answer to 3 significant digits.
2)A geochemist in the field takes
a 21.0 mL sample of water from a rock pool lined
with crystals of a certain mineral compound X.He notes the
temperature of the pool, 19.° C and caps the sample
carefully. Back in the lab, the geochemist first dilutes the sample
with distilled water to 300. 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 2.3 g
- Using only the information above, can you calculate the
solubility of X in water at 19.° C ?yes or
no?
If you said yes, calculate it.Be sure your answer
has a unit symbol and 2 significant digits.?
