How much of the 8% solution should we use to make 100g of a 3% solution? this is all i have don't ask me any questions i don't know anything else about this

Let the unknown amount be 'x' grams.

According to the question,

x of 8% solution should be used to make 100g of a 3% solution.

Let us find x of 8%

=(Equation 1)

Now, we will find 100g of a 3%

g (Equation 2)

Now, equating equations 1 and 2,

x = 37.5 grams

practice. practice. practice.

logv3(x+2)=1

rewrite in exponential form:

logb(x) = y is equal to b^y =x

b = 3, y = 1

now solve for x:

3^1 = x+2)

x = 3-2

x = 1
