If i have 8.61 moles of c6h12o6, how many moles of h2o are needed?

Find the RMM of both C6H12O6 and H2O you have the moles given cross multiply and you will get the answer

If the water vapor content stays the same and the temperature drops, then the relative humidity increases. its vise versa.if the water vapor content stats the same and the temperature rises, the relative humidity decreases. so, yes, i'd say that temperature and humidity have a strong relationship.
