Answer:
2193.8 PSI is the pressure in the tank
Explanation:
We apply the Ideal Gases Law to solve this:
P . V = n . R . T
T° is the temperature in K, so we must do the conversion:
35°C + 273 = 308K
P . 1650L = 9750 mol . 0.082 L.atm/mol.K . 308K
P = (9750 mol . 0.082 L.atm/mol.K . 308K) / 1650L → 149.24 atm
Let's make the conversion:
1 atm = 14.7 PSI → 149.24 atm . 14.7 PSI / 1 atm = 2193.8 PSI

Answer:
200.87 g
Explanation:
In order to calculate the mass of ice that could be melted by using 67,000 J of energy, we will use the following expression.
Q = ΔH°f × m
where,
- Q: heat required (67,000 J)
- ΔH°f: enthalpy of fusion of water (333.55 J/g)
67,000 J of energy can be used to melt 200.87 grams of ice.
