The volume of 0.2 moldm^-3 HxA required to completely neutralise 30cm3 of 0.1 moldm^-3 M(OH)2 is 10cm ^ -3 1. find the stiochiometry
2. the value of x
3. balanced chemical equation ​

what are the choices?

i believe it is 40–40–20%

explanation:

in the given question, the partial pressure is calculated by using the ideal gas equation, that is, pv = nrt

here, p is pressure, v is volume = 25 l, n is number of moles = 0.0104 moles, r is gas constant = -0.0821 l.atm / mol.k

t is temperature = 273 k

p = nrt / v

p = (0.0104 mol × 0.0821 l.atm / mol.k × 273 k) / 25 l

= 0.0093 atm

the answer is a and have a great day
