5.68 x 10^4 mL to L Express your answer to three sianificant fiqures and includ

olasank [31]

Answer:

5.68 × 10⁴ mL = 56.8 L

Explanation:

Volume is defined as the amount of three-dimensional closed space. The SI unit of volume is cubic metre which is denoted by the symbol m³.

According to the metric system, other units of volume include: litre (L), millilitre (mL) and cubic centimetre (cm³).

Since, 1 mL = 0.001 L = 10⁻³ L

Therefore, 5.68 × 10⁴ mL = 5.68 × 10⁴ × 10⁻³ L = 5.68 × 10 L = 56.8 L

5.68 × 10⁴ mL = 56.8 L, has three non-zero significant figures.

Anthony needs to make a solution with a concentration of 2.5m. He begins with 2.0 iters and a 8.0M solution. What final volume d

FrozenT [24]

Answer:

The final volume is 6.4 L.

Explanation:

Dilution is reducing the concentration of a chemical and is achieved by adding more solvent to the same amount of solute. In other words, dilution is the procedure that is followed to prepare a less concentrated solution from a more concentrated one, and it simply consists of adding more solvent.

In a dilution the amount of solute does not vary, and as only more volume (and mass) of solvent is being added, the concentration of the solute decreases.

In a dilution the expression is used:

Ci*Vi = Cf*Vf

where:

Ci: initial concentration
Vi: initial volume
Cf: final concentration
Vf: final volume

In this case:

Ci: 8 M
Vi: 2 L
Cf: 2.5 M
Vf: ?

Replacing:

8 M* 2 L= 2.5 M* Vf

Solving:

$Vf=\frac{8 M* 2 L}{2.5 M}$

Vf=6.4 L

<u><em>The final volume is 6.4 L.</em></u>
