Do the unit test on edg20 and got it right!
Answer:
The resulting solution contains approximately 666 g of water.
Explanation:
In the initial solution we have:
1g salt : 8g sugar : 200g water
This means that the ratios are:

In the final solution we have:
5g salt: xg sugar: yg water
The new ratios are:

Now we can calculate the amount of sugar in the final solution:

Finally, we calculate the amount of water:

Answer:
11.3 g.
Explanation:
Hello there!
In this case, since the combustion of butane is:

Thus, since there is a 1:5 mole ratio between butane and water, we obtain the following mass of water:

Therefore, the resulting mass of water is:
