Which of the following is not equal 225 g? a. 0.225 kg b. 22,500 cg c. 2.25 dkg d. 2250 dg

C) 2.25 dkg

Explanation: 1 kg = 1000 g

A)  = 225 g

B) cg stands for centigrams. 1 g = 100 cg

So,   = 225 g

C) dkg stands for decagrams. dag is also used in place of dkg which also means decagram.

1 dkg = 10 g

 = 22.5 g

D) dg stands for decigram.

1 g = 10 dg

 = 225 g

On converting all the given mass units to grams, we see that it's choice C which is not equal to 225 g and so it is the right choice.
