1. Leon tests the hummingbirds' preference
for different concentrations of sugar.
He makes another sugar solution that
has 200 g sugar and 2 L of water. What
is the concentration of this sugar
solution?

Answer 1

The concentration of this sugar solution is 9.09%.

Explanation:

The amount of sugar in the solution = 200 g

The amount of water in the solution =2 L

Now, 1 L = 1000 g

So 2 L = 2 x 1000 g = 2000 g

⇒The amount of water in the solution = 2000 g

So, the total weight of solution = Weight of ( sugar + water)

= 200 g + 2000 g = 2200 g

Now,
`\textrm{ Concentration of Sugar in solution}  = \frac{\textrm{Total amount of Sugar}}{\textrm{Total weight of solution}}  * 100`

=
`(200g)/(2200g)  * 100 = 9.09`

Hence, The concentration of this sugar solution is 9.09%.
