Cannot read multiple I2C sensor data

Hi,

I am using multiple I2C sensor MQ-9 Carbon Monoxide Combustible Gas Sensor,MQ-2 Propane Butane Methane Alcohol Gas Sensor in my recent project.
How to get multiple I2C sensor readings using single arduino nano on serial monitor.Can you provide the basic code to send multiple I2C sensor data to serial monitor.

The basic code for your project is to do research into how many I2C address your sensor can be configured for. Then you'd want to do research into multiplexers and how to use them

I smell the NCD advertiser again.
