Answer:
5.231 L.
Explanation:
- Molarity is the no. of moles of solute per 1.0 L of the solution.
<em>M = (no. of moles of KCl)/(Volume of the solution (L))</em>
<em></em>
M = 6.5 M.
no. of moles of solute = 34.0 mol,
Volume of the solution = ??? L.
∴ (6.5 M) = (34.0 mol)/(Volume of the solution (L))
∴ (Volume of the solution (L) = (34.0 mol)/(6.5 M) = 5.231 L.
Answer:
5280 feet per mile. 5280 feet divided 60 minutes then divide by 60 gives you the feet per second. multiply by 5.... 7 and 1/3 feet in 5 seconds.
Answer:
3 × 10 L
Explanation:
Step 1: Given and required data
- Moles of Xenon gas (n): 4.5 mol
- Pressure of the gas (P): 5 atm
- Ideal gas constant (R): 0.082 atm.L/mol.K
Step 2: Convert "T" to Kelvin
When working with gases, we need to use the absolute temperature. We can convert Celsius to Kelvin using the following expression.
K = °C + 273.15
K = 77°C + 273.15 = 350 K
Step 3: Calculate the volume (V) of the tank
We can calculate the volume occupied by the gas using the ideal gas equation.
P × V = n × R × T
V = n × R × T/P
V = 4.5 mol × (0.082 atm.L/mol.K) × 350 K/5 atm = 3 × 10 L
