Chemistry acidently touched math;
1.what is the percentage concentratio in the ff solution: 2g sucrose in 80g of water
2.what is the percentage concentration in the ff solution: 5ml isopropghyll alcohol in 90ml of water

im pretty sure its

(8,15)

step-by-step explanation:

d 25 pi/6

step-by-step explanation:

the diameter is 10 inches

the radius is 1/2 of the diameter or 5 inches

the area of the circle is

a = pi r^2

  = pi 5^2

  = 25 pi

the slice is 60 degrees of the entire circle.

60 degrees out of 360   60/360 = 1/6

the area of the slice is 1/6 of the circle

a slice = 1/6 a circle

a slice = 1/6 * 25 pi

the surface area is 124cm²

step-by-step explanation:

length: 4cm

width: 9cm

height:   2cm
