What is the mass of silver bromide agbr precipatated from 3.96 g of iron (iii) bromide febr3 ? febr3 + agno3 = agbr + fe(no3)3

First, write a balanced equation
FeBr3 + 3AgNO3 -> 3AgBr + Fe(NO3)3

Find the number of moles of FeBr3 we started with to find the number of moles of AfBr we end up with (we need to build a ratio)

3.96g FeBr3 / 295.55 g/mol * 3 mol AgBr / 1 mol FeBr3 * 187.77 g /mol = 7.55 g AgBr

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.
