Answer:
The answer is 2939 moles.
Explanation:
To obtain the moles from these values you should apply the ideal gas formula because in a scuba tank all gas that you have inside is the air:
PV= nRT. (1)
Thus the moles number, n, is:
n = PV/ RT (2)
Where:
P is pressure: 195 atm;
V is volume: 350 L,
R is gas constant: 0,082 atm×L / mol×K
And T is temperature: 10°C, that must be converted in k, thus:
10°C + 273,15 = 283,15 K
Replacing these values in (2) the moles number, n, is:
2939 moles of air
