. 20 mL ethanol in 60 mL solution
goldenfox [79]

The solution is the mixture of the solute into the solvent particles. In 60 mL solution, 59.8 mL of solvent is added.

<h3>What are solute and solvent?</h3>

Solute and solvent are the components of a solution. They react and mix together to produce a homogenous mixture. The solute is a substance that is added to the solvent.

Solvents are substances that dissolve the added solute in them to make a homogenous solution.

Given,

Volume of Solute = 0.20 mL

Volume of Solution = 60 mL

The volume of solvent is calculated as:

Volume of solvent = Volume of solution - Volume of solute

= 60- 0.20

= 59.8 mL.

Therefore, 59.8 mL of solvent is present in 60 mL of solution.

A container containing 5.00 L of a gas is collected at 100 K and then allowed to expand to 20.0 L. What must the new temperature
Arte-miy333 [17]

Answer:

400 K

Explanation:

Charles's law states:

A determined volume of a gas is directly proportional to its temperature, while we have constant pressure.

V₁ / T₁ = V₂ / T₂

We replace data:

5 L / 100K = 20L / T₂

T₂ = 20L . 100K / 5 L

T₂ = 400 K

The volume was quadrupled, so the temperature did.

If we want T° at Celsius degree:

400 K - 273 = 127°C

The Solar System[b] is the gravitationally bound system of the Sun and the objects that orbit it, either directly or indirectly.[c] Of the objects that orbit the Sun directly, the largest are the eight planets,[d] with the remainder being smaller objects, the dwarf planets and small Solar System bodies. Of the objects that orbit the Sun indirectly—the natural satellites—two are larger than the smallest planet, Mercury.[e]
