Answer : The statements include exact numbers are:

There are 1000 mm in 1 m.

There are 453.59 g in 1 lb.

There are 60 minutes in 1 hour.

Explanation:

Exact numbers : It is a defined or integer value which comes from counting numbers of objects.

They have an infinite number of significant figures.

For example : 12 eggs in a dozen, 1000 g in a kilogram and 2.54 cm in an inch.

(1)  There are 1000 mm in 1 m.

(2) Jane is 63 in tall.

(3) There are 453.59 g in 1 lb.

(4) There are 60 minutes in 1 hour.

In the given statements, the statements 1, 3 and 4 include exact numbers but statement 2 is not include exact number because it is the measured value.

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 wiling to try and you : )
