How can i calculate the percent concentration of solution?

m solute= 15g
m solution =100g

You should calculate in this way

m solute= 15g

m solution = 100g

C%= m solute/m solution  *100%

C% = 15/100 *100 = 15%

C%= 15%

You should calculate in this way

m solute= 15g

m solution = 100g

C%= m solute/m solution  *100%

C% = 15/100 *100 = 15%

C%= 15%

you must divide the mass of the solute by the mass of the solution and then multiply by 100

15/100=0.15

0.15 x 100 = 15%

you must divide the mass of the solute by the mass of the solution and then multiply by 100

15/100=0.15

0.15 x 100 = 15%

A.) 3.2 pounds package has a shipping cost of $4.13. We can't use the cost assigned to 3 lbs because the package is over 3 lbs but it is not over 4 lbs so we use the cost of 4lbs.

b) It is better to use a line graph where x values represent the weight in pounds and the y values represent the cost.

c) f(x) = 2.69 + 0.48(x-1)

d) domain is the x values; range is the y values
