Answer:
342 grams of sugar are needed.
Step-by-step explanation:
This really should be in chemistry. Math types may not know any chemistry.
Step One
Find the number of moles needed in a solution of the givens.
<em><u>Givens</u></em>
V = 2.00 L
C = 0.500 moles / Liter
<em><u>Formula</u></em>
n = C * V
<em><u>Sub and Solve</u></em>
n = 2 * 0.5 = 1 mole
Since you need just 1 mole, the answer is 342 grams of sugar are needed to put into a solution of 2 Liters with a concentration of 0.500
The answer is to 3 decimal places so 342 is the answer.
Answer:
176 cm
Step-by-step explanation:
You can use the Pythagorean theorem to find the hypotenuses of each triangle by sibstituting the given lengths of each leg.
-2x+8 = x-1 substitute for one of the y
-8. -8 solve for x
-2x = x -9
+x =. +x
-1x = -9
/-1. =. /-1
x=9
y=-2(9)+8 now solve for y by putting x
y= 18 +8 in the one of the original
y= 26 equations.
(9,26)
You must start with =. The answer is D, =
