Edited after some bad maths and incorrect numbers...
Assuming mid cage 10 speed 105 mech, specs say...
Maximum low sprocket 28t
Maximum front difference 22T, total capacity (chain wrap) 39t
Chain wrap = (large chainring – small chainring) + (large rear cog – small rear cog)
(50-34) + (32-11) = 37
37 < 39 so the chain wrap works, but 32 > 28t max low sprocket so you might run into trouble there.
