Complete the table. d. 3.345 kJ _J _mJ

Guida verificata passo dopo passo

Step 1: Understand the units involved. We are converting kilojoules (kJ) to joules (J) and millijoules (mJ).

Step 2: Recall the conversion factors: 1 kJ = 1000 J and 1 J = 1000 mJ.

Step 3: Convert 3.345 kJ to joules by multiplying by the conversion factor: 3.345 kJ * 1000 J/kJ.

Step 4: Convert the result from joules to millijoules by multiplying by the conversion factor: result in J * 1000 mJ/J.

Step 5: Fill in the table with the calculated values for joules and millijoules.
