The molar mass pf hgo is 216.59. the molar mass of o2 is 32.00 g/mol. how many moles of hgo are needed to produce 250.0 g of o2?

Molar mass HgO is 216.59 g/mol
Molar mass of O2 is 32.00 g/mol
250.0 g of O2 
Required: Moles of HgO

Balanced equation is:
2HgO → 2Hg+ O2 
250g O2(1 mole O2/32.00 g/mol O2)(2 moles HgO/1 mol O2) = 15.63 moles HgO

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.
