Answer:
57.6ml
Explanation:
Using dilution formula
C1V1 = C2V2
C1 = 2.903 M, V1 = ? , C2 = 0.3344 M , V2 = 500ml
2.903 × V1 = 0.3344 × 500
V1 =( 0.3344 × 500)/ 2.903
= 57.5956
≈ 57.6ml

Answer:
6. 25.8 mL.
7. 16.4 mL.
8. 24.0 mL.
Explanation:
6. Determination of the volume of HCl.
Mass = 30 g
Density = 1.164 g/mL
Volume =..?
Density = mass /volume
1.164 = 30 / volume
Cross multiply
1.164 × volume = 30
Divide both side by 1.164
Volume = 30 / 1.164
Volume = 25.8 mL
7. Determination of the volume of H2SO4.
Mass = 30 g
Density = 1.834 g/mL
Volume =..?
Density = mass /volume
1.834 = 30 / volume
Cross multiply
1.834 × volume = 30
Divide both side by 1.834
Volume = 30 / 1.834
Volume = 16.4 mL
8. Determination of the volume of HNO3.
Mass = 30 g
Density = 1.251 g/mL
Volume =..?
Density = mass /volume
1.251 = 30 / volume
Cross multiply
1.251 × volume = 30
Divide both side by 1.251
Volume = 30 / 1.251
Volume = 24.0 mL
