Answer:
6. 25.8 mL.
7. 16.4 mL.
8. 24.0 mL.
Step-by-step 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
