Answer: 1.11 atm
Explanation:
The unit of pressure include kilopascal (kPa), atmospheres (atm), mmHg etc
Now, given that:
Air pressure = 113 KPa
Convert kPa to atm
If 101.325 kPa = 1 atm
113 kPa = Z atm
To get the value of Z, cross multiply
Z atm x 101.325 kPa = 1 atm x 113 kPa
Z = ( 1 atm x 113 kPa) / 101.325 kPa
Z = 1.11 atm
Thus, the pressure is 1.11 atm
D = m / V
d = 1300 g / 743 cm³
d = 1.749 g/cm³
Answer:
H2O2
Explanation:
2 hydrogen, 2 oxygen wikipedia it
Since temperature is held constant; Boyle's law can be expressed as: P 1 * V 1 = P 2 * V 2
Where P1 = 625 and V1 = 0.5 L
V2 = 925 * 10^(-3) = 0.925 L and P2 = ?
So P2 = (P1 * V1)/P2
P2 = (625 * 0.5)/0.925
P2 = 337.83 my hg
