A sample of oxalic acid, H2C2O4, was analyzed using a standardized solution of KMnO4. 25.0mL of oxalic acid is titrated after heating. 12.30 mL of a 0.0226 M KMnO4 was added to the sample when a faint pink color was observed. The balanced equation for this reaction is shown: 6 H+(aq) + 2 MnO4-(aq) + 5 H2C2O4(aq) → 10 CO2(g) +8 H2O(l) + 2Mn2+(aq)

Question: If the density of the oxalic acid solution was 1.00 g/mL, what was the percentage by mass of oxalic acid in the solution?

0.0027 i hope this right good luck

a rain shadow is a dry region of land on the side that is protected against the prevailing winds of a mountain range. the prevailing winds are the winds that occur most of the time in a particular place of the earth

prevailing winds carry air toward the mountain range. as the air rises up over a mountain range, the air cools, water vapor condenses, and clouds form. on this side of the mountains, called the windward side, precipitation falls in the form of  rain  or snow. this dry air produces a  rain shadow.

the cold front replaces the warmer air at the ground level changing the wind to be breezy and denser.there is also an immediate drop in the temperature.
