The temperature of 300 milliliters of a gas at 400K is increased to 800K, pressure remaining constant. What will the new volume

Annette [7]

Answer:

V₂ = 600 mL

Explanation:

Given data:

Initial volume = 300 mL

Initial temperature = 400 K

Final temperature = 800 K

Final volume = ?

Solution:

The given problem will be solve through the Charles Law.

According to this law, The volume of given amount of a gas is directly proportional to its temperature at constant number of moles and pressure.

Mathematical expression:

V₁/T₁ = V₂/T₂

V₁ = Initial volume

T₁ = Initial temperature

V₂ = Final volume

T₂ = Final temperature

Now we will put the values in formula.

V₁/T₁ = V₂/T₂

V₂ = V₁T₂/T₁

V₂ = 300 mL × 800 K / 400 k

V₂ = 240000 mL.K / 400 K

V₂ = 600 mL

A student mixed 115 g of sugar, 350 g of water and 5 g of spices. What will be the mass of the solution?

jenyasd209 [6]

Answer:

$m_{solution}=470g$

Explanation:

Hello,

In this case, a solution is formed when a solute is completely dissolved in a solvent, thus, for this situation, the sugar is the solute and the water the solvent but in addition to them we find spices which are also considered in the total mass of the solution. In such a way, for computing the total mass we must add the mass of three constituents (115 g sugar, 350 g water and 5 g spices) as shown below:

$m_{solution}=115g+350g+5g\\\\m_{solution}=470g$
