An unknown solution has a pH of two. How would you classify this solution?

2 answers:

7 0

I would say it is an acidic solution. Anything with a pH between 0 and 7 is considered acidic, 7 is neutral, and 7-14 is basic.

This would be an acidic solution since the pH level would be under 7, which means that the solution would be acidic

Which of the following is not equal to 485 L?

ELEN [110]

Answer:

$4.85 * 10^4\ mL$

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

$\frac{485KL}{1000} = \frac{485000L}{1000}$

$0.485KL = 485L$ ---- 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
