Final answer:
To calculate the volume of carbon dioxide gas collected, use the ideal gas law equation PV = nRT. Convert the temperature to Kelvin and solve for the number of moles. Then, convert the number of moles to the volume of gas using the molar volume of a gas at STP.
Step-by-step explanation:
To calculate the volume of carbon dioxide gas collected, we can use the ideal gas law equation: PV = nRT, where P is the pressure, V is the volume, n is the number of moles, R is the ideal gas constant, and T is the temperature in Kelvin.
In this case, the pressure is 1 atm, and we can assume that the volume of the gas is the same as the volume collected (343 milliliters). The temperature is given in Celsius, so we need to convert it to Kelvin by adding 273.15. Plugging in the values, we can solve for the number of moles using the ideal gas law.
Once we have the number of moles, we can convert it to the volume of the gas using the molar volume of a gas at STP, which is 22.414 liters/mol. Therefore, the volume of carbon dioxide gas collected is 0.343 liters, which is option D).
