Number of mole : mass/ molar mass
87g/ (2 x 16) = 2.719 mol
volume = number of mole x molar volume
volume = 2.719 x 22.4
volume = 60.906 L

Answer:
the percent error expected from each of theses person's body:
in homes:
% E = 0.14267 %
in doctor's office:
% E = 0.257 %
Explanation:
- ° C = ( ° F - 32 ) * (5/9)
- % E = ( | true - exp | / true ) * 100
- body temp = 38.9 ° C = 102.02 ° F
thermometer used in homes:
⇒ T = 102.02 ° F +/- 0.1 ° F = 102.12 ° F ∧ 101,92 ° F
⇒ T = 102.12 ° F = 38.9555 ° C
⇒ % E = ( | 38.9 - 38.9555 | ) / 38.9 ) * 100 = 0.14267 %
in the doctor's oficce:
⇒ T = 38.9 ° C +/- 0.1 ° C = 39 ° C ∧ 38.8 ° C
⇒ % E = (( | 39 - 38.9 | ) / 38.9 ) * 100 = 0.257 %
