What you have to keep in mind is that
pH = - log[H+]
so 3.75 = -log[H+], we get [H+]=
,
that is [H+]≈1.77827941×
(i see this result on calculator)
this is just what you want!
It would take 8 antacid tablets to produce 120 mL of CO2 gas.
Acetic acid is formed when wine is left exposed to oxygen for extended periods.
Answer:-
48.72 L
Explanation:-
We need to use the relation PV = nRT
We are given Pressure P = 100 KPa.
We are given Temperature T = 293 K
We know Universal Gas constant R = 8.314 L KPa K-1 mol-1
Mass of water = 36 gram
Chemical formula of water = H2O
Molecular weight of water = 1 x 2 + 16 x 1 = 18 g / mol
Number of moles of water = 36 gram / (18 g / mol)
= 2 mol
Plugging in the values we get
100 KPa x V = 2 mol x 8.314 L KPa K-1 mol-1 x 293 K
V = (2 mol x 8.314 L KPa K-1 mol-1 x 293 K) / (100 KPa)
= 48.72 L
