6 граммов.....................

Answer 3

To find out how much salt is present in 300g of the solution, we can use the concept of proportionality.

Let's set up a proportion based on the given information:

Amount of salt (in grams) / Total weight of the solution (in grams) = Amount of salt (in grams) / Total weight of the solution (in grams)

We know that in 4000g of the solution, there are 80g of salt:

80g / 4000g = Amount of salt in 300g / 300g

Now, let's solve for the unknown amount of salt in 300g of the solution:

80g / 4000g = x / 300g

To find 'x' (the amount of salt in 300g of the solution), cross-multiply and solve for 'x':

80g * 300g = 4000g * x

24000g = 4000g * x

Now, isolate 'x' by dividing both sides by 4000g:

x = 24000g / 4000g

x = 6g

So, there are 6 grams of salt in 300 grams of this solution.
