The Krebs cycle runs twice to break down one molecule of glucose.
six
The Calvin cycle needs to be run through six times to produce one molecule of glucose. This is because each turn of the Calvin cycle fixes one molecule of carbon dioxide, and glucose has six carbons in its structure.

A single glucose molecule is able to drive the Krebs cycle 2 times. The Krebs Cycle is the series of chemical reactions that take place to provide all aerobic organisms with the ability to make energy.

It occurs 2x per glucose molecules.. But the thing is, I didn't know how that happen
Six. (The info below is taken directly from the Wikipedia article on the Calvin cycle. The immediate products of ONE turn of the Calvin cycle are: 2 x glyceraldehyde-3-phosphate (G3P) molecules 3 x ADP 2 x 2 NADP+ (ADP and NADP+ are regenerated in the light-dependent reactions). Each G3P molecule is composed of 3 carbons. In order for the Calvin cycle to continue, RuBP (ribulose 1,5-bisphosphate) must be regenerated. So, 5 of the 6 carbons from the 2 G3P molecules are used for this purpose. Therefore, there is only 1 net carbon produced to play with for each turn. To create 1 extra G3P requires 3 carbons, and therefore 3 turns of the Calvin cycle. To make one glucose molecule (which can be created from 2 G3P molecules) would require 6 turns of the Calvin cycle. Surplus G3P can also be used to form other carbohydrates such as starch, sucrose, and cellulose depending on what the plant needs.
6 cycles are required if you consider or start from 1 CO2 , but 2 cycles if you start from 3 CO2 .
Water is one such molecule, being H2O. The molecules of sucrose and glucose also have the same two to one ratio of hydrogen to oxygen. Sucrose is C12H22O11, and glucose is C6H12O6.
