Question
14 of 15 ic Table of the Part A a1.15 % (mv) H2SO4 solution prepared from 10 9 mL of a 19 4 % H2SO, solution Express your answer to three significant figures and include the appropriate units. Value Units Submit Part B a 0.50 M HCI solution prepared from 49 mL of a 8.7 M HCI solution Express your answer to two significant figures and include the appropriate units. alue Units Submit Request Answer ? Part C a 1.9 M NaOH solution prepared from 60.0 mL of a 16 M NaOH solution Express your answer to two significant figures and include the appropriate units.Explanation / Answer
part A
C1V1 = C2V2
c1 = initial concentration of solution = 19.4% m/v
V1 = initial volume of solution = 10.9 ml
C2 = final concentration of solution = 1.15% m/v
V2 = final volume of the solution = ?
19.4*10.9 = 1.15*V2
V2 = 184 ml
answer: V2 = 1.8*10^2 ml
part B
C1V1 = C2V2
c1 = initial concentration of solution = 8.7 M
V1 = initial volume of solution = 49 ml
C2 = final concentration of solution = 0.5 M
V2 = final volume of the solution = ?
8.7*49 = 0.5*V2
V2 = 853 ml
answer: 8.5*10^2 ml
part C
C1V1 = C2V2
c1 = initial concentration of solution = 16 M
V1 = initial volume of solution = 60 ml
C2 = final concentration of solution = 1.9 M
V2 = final volume of the solution = ?
16*60 = 1.9*V2
V2 = 505 ml
answer: 5.0*10^2 ml
part D
C1V1 = C2V2
c1 = initial concentration of solution = 5.4% m/v
V1 = initial volume of solution = 22 ml
C2 = final concentration of solution = 1.3% m/v
V2 = final volume of the solution = ?
5.4*22 = 1.3*V2
V2 = 91.4 ml
answer: 9.1*10^2 ml
