How many grams of solute are needed to prepare 2oz of 8% iodine solutions

  4.732 grams

Step-by-step explanation:

2 US fluid ounces is exactly 59.147059125 mL of volume. 8% of that volume is 4.73176473 mL.

For a solution of this type, where 1 g/100 mL is considered a 1% solution this is the number of grams of solute needed.

  About 4.732 grams of solute are needed to prepare 2 fl oz of 8% solution.

We have assumed that 1 gram of solute gives you 1 gram of iodine. Depending on the exact solute used, that may or may not be the case.

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is
