How many milligrams of sodium are contained in 3 g of nacl?

mNaCl: 23g + 35,5g = 58,5 g/mol
mNa: 23 g/mol

23g Na 58,5g NaCl
Xg Na 3g NaCl
X = (3×23)/58,5
X = 1,1795g = 1179,5 mg

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.
