If 4. 12 l of a 0. 850 m-h3po4 solution is be diluted to a volume of 10. 00 l, what is the concentration the resulting solution?.

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

i'm pretty sure its b i might be wrong though!

um i think it might be a car?

the answer is d.) potassium
