How many liters of h2 gas, collected over water at an atmospheric pressure of 752 mmhg and a temperature of 21.0°c, can be made
Shalnov [3]

The answer is V = 0.6 L


The explanation:


1- First we will get P (H) :


p (H) = p total - p (H2O)


= 752 mmHg - 18.65 mmHg


= 733 mmHg


= 733 mmHg X (1 atm / 760 atm) = 0.964 atm


2- then when the reaction equation is:


Zn(s)+2HCl(aq) -> H2(g)+ZnCl2(aq)


so, then 1 mole of Zn will produce 1 mole of H2.


so, we need to get first the mole of Zn:


mole Zn = mass / molar mass


= 1.566g / 65.38g/mol

= 0.02395mol


∴ 0.02395 mol of Zn will produce 0.02395 mol of H2


by using the ideal gas equation we can get the volume V :


when :


PV = nRT


when T is the temperature = 21 + 273 = 294 K


and R is the ideal gas constant = 0.0821 L atm /K mol


and n is the number of moles = 0.2395 mol


and P is the pressure = 0.964 atm


so, by substitution:


V = (0.02395 moles H2)(0.0821 L atm / K mole)(294 K) / (0.964 atm)


= 0.6 L
