Answer:
Grade Point Average = 2.21
Step-by-step explanation:
GPA (Grade Point Average) would be:
multiplying the individual point with respective credit hours and SUMMING THEM
Then
dividing all of them by the total number of credit hours
Hence,
5(1) + 3(3) + 1(2) +5(3) = 5 + 9 + 2 + 15 = 31 [note: the numbers in parenthesis is the points and outside the parenthesis is the credit-hours]
Now
total credit hours is 5 + 3 + 1 + 5 = 14
GPA = 31/14 = 2.21
The answer to this should be 1.51
Answer: 248mL
Step-by-step explanation:
Given:
Concentration of buffer solution Cs = 1.24%w/v of boric acid
Concentration of boric acid solution Cb = 5 % w/v boric acid
For 1 liter of buffer solution, the weight of boric acid needed is:
mb = 1 × 1.24 = 1.24 unit weight
mb = Cb × Vb .....1
Cb = concentration of boric acid solution.
Vb = volume of boric acid solution needed.
mb = weight of boric acid needed.
From equation 1.
Vb = mb/Cb
Vb = 1.24/5
Vb = 0.248L
Vb = 248mL
Answer:
A. 216 cm³
Step-by-step explanation:
The volume of a cube is the cube of the side length:
V = s³ = (6 cm)³ = 216 cm³
