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:
x=10,-4
Step-by-step explanation:
Move all of the terms to the left and then set x to zero . Then set each factor equal to zero .
Answer:
it is 9
Step-by-step explanation:
adding 79 and 10 and subsequently subtracting 72 and 8 to get 9
I think the answer is -44n+2
Round 2.81 to 2.8 and 3.72 to 3.7. Add both together to get 6.5
