Looking at the name of an acid, how do you know if it only contains two elements, or if it contains more than two? ?

Explanation:the way you know if  a element in this case a type of acid is if on the periodic table in the bottom left corner it will tell you

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
