water is added to a graduated cylinder followed by a metal sample. the graduated cylinder from before and after the metal sample was added are both shown. use volume displacement to determine the volume of this metal sample. be sure to report your volumes to the nearest 0.1 ml.\nv_initial = \nv_final = \nv_metal = \ntools\nx10^y
Answer
Explanation:
Step1: Read initial volume
From the "Before" image of the graduated - cylinder, the meniscus of the water is at 25.0 mL. So, $V_{initial}=25.0$ mL.
Step2: Read final volume
From the "After" image of the graduated - cylinder, the meniscus of the water (with the metal sample added) is at 28.0 mL. So, $V_{final}=28.0$ mL.
Step3: Calculate metal volume
The volume of the metal sample is given by the difference in the final and initial volumes of water in the graduated - cylinder, $V_{metal}=V_{final}-V_{initial}$. Substituting the values, we get $V_{metal}=28.0 - 25.0=3.0$ mL.
Answer:
$V_{initial}=25.0$ mL $V_{final}=28.0$ mL $V_{metal}=3.0$ mL
