This problem can be solved using the combined gas law, which states that the ratio of the product of pressure and volume to temperature is constant for a given amount of gas. The combined gas law can be written as follows:

P1 * V1 / T1 = P2 * V2 / T2

Where:
P1 = initial pressure
V1 = initial volume
T1 = initial temperature
P2 = final pressure
V2 = final volume
T2 = final temperature

Given in the problem are:
P1 = 1200.0 mm Hg
V1 = 85.00 mL
T1 = 90.0 °C = 90 + 273.15 = 363.15 K (converted from Celsius to Kelvin)
P2 = 850.0 mm Hg
V2 = 350.00 mL

We are asked to solve for T2.

Substituting the given values into the combined gas law gives:

1200 * 85 / 363.15 = 850 * 350 / T2

Solving for T2 gives:

T2 = 850 * 350 * 363.15 / (1200 * 85) = 315.15 K

Therefore, the final temperature would be 315.15 K. To convert this back to Celsius, subtract 273.15:

315.15 K - 273.15 = 42.0 °C

So, the final temperature would be 42.0 °C.
