This question is incomplete, the complete question is;

A household item uses 321 watts of electricity. This item is used for 27 hours each week. How much CO2 will be produced each week from this item? (assume 1.37 pounds of CO2 is produced per KWH of electricity used)

Answer: 11.87 lbs of CO2 will be produced each week from this item

Step-by-step explanation:

Given that;

Average wattage Wattage of the item = 321 watts

Time used = 27 hours each week

CO2 produced each week = ?

so;

Total electricity consume = 321 × 27 = 8667 watt = 8.667 kWh

given that; 1.37 pounds of CO2 is produced per KWH of electricity used

hence; CO2 generated by our item will be;

⇒ 8.667 kWh × 1.37

= 11.87 lbs

Therefore, 11.87 lbs of CO2 will be produced each week from this item
