What variable did the researchers intentionally vary in the experiment, and what are the units for this variable? what variable did the researchers intentionally vary in the experiment, and what are the units for this variable? inorganic phosphate (inorganic phosphate) concentration, in micromoles per milliliter of sampled buffer glucose 6-phosphate concentration, in micromoles per milliliter of sampled buffer ph, in ph units time of reaction, in minutes?

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 correct option is c.

isotopes refers to different forms of the same element with the same atomic number but different mass number as a result of difference in their neutron numbers. isotopes have different relative atomic mass but share the same chemical properties.
