Final answer:
To calculate the volume of krypton at standard temperature and pressure (STP), we can use the ideal gas equation.
Step-by-step explanation:
To calculate the volume of krypton (Kr) at standard temperature and pressure (STP), we can use the ideal gas equation:
V = (nRT)/P
Where:
- V is the volume
- n is the number of moles of gas
- R is the gas constant
- T is the temperature
- P is the pressure
First, we need to convert the mass of krypton to moles using its molar mass. The molar mass of krypton is 83.80 g/mol. So, the number of moles is given by:
n = mass/molar mass = 375.0 g / 83.80 g/mol = 4.47 mol
Plugging in the values:
V = (4.47 mol x 0.08206 L atm mol-1 K-1 x 273.15 K) / 1 atm
V = 0.992 L
Therefore, the volume of 375.0 g of krypton at STP is 0.992 liters.
