How do solve the uncertainly of a number??

For example, given a measurement of 14.3 millimeters, plus or minus 5 percent, the relative uncertainty is 5 percent. Multiply the measurement by the relative uncertainty to obtain the absolute uncertainty. In this case, multiply 14.3 millimeters by 5 percent, which equals 0.7 millimeters

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
