Answer:-
0.229 L
Explanation:-
Molar mass of AgBr = 107.87 x 1 + 79.9 x 1
=187.77 grams mol-1
Mass of AgBr = 150 grams
Number of moles of AgBr = 150 grams / 187.77 gram mol-1
= 0.8 mol
The balanced chemical equation is
NaBr (aq) + AgNO3 (aq)--> AgBr(s) + NaNO3(aq)
From the equation we can see that
1 mol of AgBr is produced from 1 mol of AgNO3.
∴ 0.8 mol of AgBr is produced from 1 x 0.8 / 1 = 0.8 mol of AgNO3.
Strength of AgNO3 = 3.5 M
Volume of AgNO3 required = Number of moles / strength
= 0.8 moles / 3.5
=0.229 L
Explanation:
The amount of moisture present in air at a given temperature is known as humidity.
Whereas relative humidity is the amount of percentage of moisture it contains when compared to the maximum moisture it can contain at a given temperature.
Also % Relative humidity (RH) =
where, P = the partial pressure of water vapour
= the equilibrium vapor pressure at a particular temperature.
Accrding to the Clausius-Clapeyron equation, decreases with decrease in temperature.
Hence, it means that at super-cooled conditions the %RH would be 100%.
On the other hand, the temperature will be very high at super-heated conditions.
Hence, will be high hence %RH will be low.
It is also known that at saturated condition, P =
Therefore, %RH is 100.
Thus, we can conclude that when the relative humidity is 90%, we say the air is humid.
