Answer:
C. 2.70 g/mL
Explanation:
Density is the ratio between the mass of a substance and the volume it occupies. Based on Archimedes' volume, the displaced volume of the aluminium is the volume it occupies. To solve this question we must find the difference in volume between initial volume of water = 30mL and final volume of water + aluminium = 39.26mL. This difference is the volume of the aluminium. With its mass we can find density:
39.26mL - 30mL = 9.26mL
Density = 25.00g / 9.26mL =
2.70g/mL
Right answer is:
<h3>C. 2.70 g/mL

Answer:
V acid = 51.471 mL
Explanation:
- %v/v = [(compoud volumen)/(solution volume)]×100
∴ V solution = 387 mL
∴ %v/v = 13.3 %
compund volume:
⇒ (V acid)/( V sln) = 0.133
⇒ V acid = (0.133)(387 mL)
⇒ V acid = 51.471 mL
