My deltaL is 0.71mm = 710m
from 22 C to 35 C. I solved and got 0.39 for L0 but it says it's wrong? Help please?

my numbers were 22 degrees C, 35 degress C, and .79mm. So i did 140*13 all divided by 790 and what did i do wrong?

0.71 mm is 0.00071 m
and alpha you need to use is for steel and not for mercury there is no mention of mercury
