[AI-generated answer — Bot GPT 3.5]

To find the mass of one ball, we need to divide the total mass of the 3 balls by 3.

Total mass of the 3 balls = 6 3/10 grams

Dividing 6 3/10 by 3, we get:
6 3/10 ÷ 3 = (6 + 3/10) ÷ 3
= (60/10 + 3/10) ÷ 3
= 63/10 ÷ 3
= 63/10 × 1/3
= (63 × 1) / (10 × 3)
= 63/30
= 2 3/10

Therefore, the mass of one ball is 2 3/10 grams.
