Resolution, dots per inch,  is meaningless on its own.
If you know the target size, then you can calculate the number of dots you need 
(eg, 8x10" would be 2400x3000 dots = 7,200,000 dots). Which more or less 
translates to a file of 7.2mb.
But a 1x2" image only needs 300x600= roughly 180kb. 

LR allows you to specify dpi when printing and it allows you to specify file 
output size when doing an Export. But you need to know the target print size, 
and you need to do the calculation to determine the necessary file size.
