Question

Which of the following is not equal to 485 L?

0.485 kL
4.85 x 104 mL
48,500 cL
4.85 x 108 µL

Answer 1

`4.85 * 10^4\ mL`

Step-by-step explanation:

Given

485 L

Required

Determine the measurement not equal to 485L

`0.485\ kL`

From standard unit of conversion;

1 KL = 1000 L

Multiply both sides by 485

`485 * 1 KL = 485 * 1000 L`

`485KL = 485000L`

Divide both sides by 1000

`(485KL)/(1000) = (485000L)/(1000)`

`0.485KL = 485L` ---- This is equivalent

---------------------------------------------------------------------------------------------

`4.85 * 10^4\ mL`

From standard unit of conversion;

1000 mL = 1 L

Multiply both sides by 485

`485 * 1000 mL = 1 L * 485`

`485000\ mL = 485\ L`

Convert to standard form

`4.85 * 10^5\ mL = 485\ L`

Hence;
`4.85 * 10^4\ mL` is not equivalent to 485L

---------------------------------------------------------------------------------------------

`48500 \ cL`

From standard unit of conversion;

100 cL = 1 L

Multiply both sides by 485

`485 * 100 cL = 1 L * 485`

`48500\ cL = 485\ L`

Convert to standard form

`4.85 * 10^4\ cL = 485\ L` ---- This is equivalent

---------------------------------------------------------------------------------------------

`4.85 * 10^8 \` μL

From standard unit of conversion;

1000000 μL = 1 L

Multiply both sides by 485

`485 * 1000000uL = 1 L * 485`

`485000000uL = 485\ L`

Convert to standard form

`4.85 * 10^8\ uL = 485\ L` ---- This is equivalent

From the list of given options;

`4.85 * 10^4\ mL` is not equivalent to 485L
