Final answer:
The ratio of PV to nRT is 1:1.
Step-by-step explanation:
The ratio of PV to nRT can be determined by rearranging the ideal gas law equation PV = nRT. Dividing both sides of the equation by nRT, we get:
PV/nRT = 1.
Since the value of PV/nRT is 1, the ratio of PV to nRT is 1:1. Therefore, the correct answer is a) 1:1.
