Which of the following is not the same as 1,400 ml?
1,400 cm³
1.4 l
1.4 cm³
140 cl

1.4 cm³

Explanation:

The units of volume can be converted by:

1 L = 10 dL = 100 cL = 1,000 mL = 0.001 m³

1 m³ = 1,000 dm³ = 1,000,000 cm³ = 1,000,000,000 mm³ = 1,000 L

So, 1 mL = 1 cm³ = 0.001 L = 0.1 cL

1,400 mL = 1,400 cm³ = 1.4 L = 140 cL

since electrons are negative the answer is neagtaive
