Given:
Total solution : 1000mL
Pure acetic acid = 26mL
To find:
The percent concentration of given solution.
Solution:
We know that,

Putting the given values, we get



Therefore, the percent concentration of this solution is 2.6%.
Answer:
3/16
Step-by-step explanation:
since the question has "and" we will be multiplying two unrelated probabilities
P(gray on 1) = 1/4
P(blue on 2) = 3/4
the second probability is not affected since we are not taking away the first space after we land on it
1/4 * 3/4 = 3/16
We are given with the slope of a ramp that is equal to 2/5, that is x = 5 and y = 2. In this case, we can find the angle of elevation by using the formula: tan Ф = y/x
using a calculator (inverse tangent or arctangent), Ф = 21.8 degrees. In this case, the answer is D. 22 degrees.
Answer:
J.
Step-by-step explanation:
There is no solution because these are parallel lines.
Parallel lines never intersect and so they have no solution.
(x-8)^2+y^2=225 I'm not able to factor it
