How much of the 8% solution should we use to make 100g of a 3% solution?

The mass of 8% that will be required to make 100 g of the 3% solution is 37.5 g.

The given parameters:

The mass of the 3% of the given solution is calculated as follows;

m = 0.03 x 100

m = 3 g

The mass of 8% that will be required to make 100 g of the 3% solution is calculated as follows;

0.08x = 3

Thus, the mass of 8% that will be required to make 100 g of the 3% solution is 37.5 g.

unless you made a typo, the answers are both a and c.

step-by-step explanation:

1.5/3 is .5 whereas 3/9 is .3333333 not proportional

22/33 is .66666 and 4/6 is also .66666 proportional

2/4 is .5 whereas 142/213 is .66666 not proportional

14/7 is 2 and 7/3.5 is also 2 proportional

you could've also checked it by doing this simple division:

if the larger fraction divides with the smaller fraction to equal 1, it is proportional. so let me show you what i mean:

when i divide 22/33 by 4/6 i get 1, so we know it is proportional, and it is the same with 14/7 and 7/3.5. now if i divide 3/9 by 1.5/3 i get .66666 so therefore we know it is not proportional.

there are many ways to do this so i wanted to show you some possible ways.
