The average blood volume in the human body is about 4.9 L. Convert this volume to cubic centimeters (cm3).a. milliliters (mL)b.

CaHeK987 [17]

Answer:

a. 4900 mL; b. 4900 cm³ c. 4.9x10⁻³ m³

Explanation:

1 L = 1 dm³

4.9 L = 4.9 dm³

1 dm³ = 1000 cm³ → 4900 cm³

1 cm³ = 1 mL (4900 mL)

1 dm³ = 1x10⁻³ m³ → 4.9x10⁻³ m³

Which one of the following statements best describes a solution with a pH of 3?

zalisa [80]

Statement D is the correct option as the solution will have pH of 3. It has an H3O+ ion concentration of 1 × $10^{-3}$ mol/L and is acidic.

Explanation:

It is given in question that solution must have pH of 3. The value if being less than 7 shows that solution is acidic. The pH value of 3 indicates that given solution is highly acidic and has strong acid. Strong acid gets fully dissociated into $H_{3}$ $O^{+}$ ions.

pH of the solution is calculated as:

pH = -log10[ $H_{3}$ $O^{+}$ ]

the concentration or molarity of the hydronium ion is given as moles/litre

concentration of hydronium ion in the solution is 1 X $10^{-3}$ moles/litre

putting the values in the equation:

pH = - log10( 1 X $10^{-3}$ )

pH = 3 (acidic)

Thus it can be concluded that D option is the right answer.
