Why is it hard for scientists to change lead into gold? scientists would have to change the number of protons in lead atoms. scientists would have to change the number of electrons in lead atoms. scientists would have to change the number of neutrons in lead atoms. scientists would have to change the number of protons and neutrons in lead atoms.

a graduated cylinder.

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
