Calculate the amount of water required to prepare 500g of 2.5% solution of sugar.
Snowcat [4.5K]

(i) We start by calculating the mass of sugar in the solution:

mass of sugar = concentration × solution mass

mass of sugar = 2.5/100 × 500 = 12.5 g  

Then now we can calculate the amount of water:

solution mass = mass of sugar + mass of water

mass of water =  solution mass - mass of sugar

mass of water = 500 - 12.5 = 487.5 g

(ii) We use the following reasoning:

If       500 g solution contains 12.5 g sugar

Then    X g solution contains 75 g sugar

X=(500×75)/12.5 = 3000 g solution

Now to get the amount of solution in liters we use density (we assume that is equal to 1):

Density = mass / volume

Volume = mass / density

Volume = 3000 / 1 = 3000 liters of sugar solution

Plz help!! I really really need the help as soon as possible thank pls!! Your help matters to me pls help it’s due tomorrow morn
Assoli18 [71]

Answer:

6.Given,

Final Velocity =60m/s

Initial Velocity= 0

Time=10 sec

A=?

A=Final Velocity- Initial Velocity/time

=60-0/10

=60/10

=6m/s ans.

Explanation:

Acceleration = Final Velocity - Initial Velocity/Time

By using this Formula we can calculate Acceleration.

The graph shows the distribution of energy in the particles of two gas samples at different temperatures, T1 and T2. A, B, and C
soldi70 [24.7K]

Based on the information given regarding the energy, the true statement is C.  "The number of particles able to undergo a chemical reaction is less than the number that is not able to."

<h3>What is energy?</h3>

It should be noted that energy is the quantitative property that must be transferred to a body to perform work on the body.

In this case, the graph is shown with two inverted graph curves running close to each other, and one of the curves labeled T1 is slightly more spread out than the other labeled T2.

Here, T1 is the only sample with a particle able to react. Particle B is more likely to participate in the reaction than particle A and the number of particles able to undergo a chemical reaction is less than the number that is not able to.
