Five identical bars have a mass of 1.25 kilograms, so nine have a mass of 2.25 kilograms.✓Правильный ответ
Объяснение
A bottle holds 6 divided by 8, or 0.75 litres, so fourteen hold 10.5 litres; one bar has a mass of 1.25 divided by 5, or 0.25 kilograms, so nine have a mass of 2.25 kilograms. The candle prediction is the closest false claim because three times as many identical candles would burn 54 grams, not 24 grams.
