Question

You are provided with a glass stopper and a measuring cylinder how will you proceed to find the density of stopper

Answer 1

Answer:

Explanation:

You will pour water into the measuring cylinder up to about 250cubic cm. insert the glass stopper in the measuring cylinder then mark and record. Then  sabtract the initial volume of water from that of the water and the glass stopper to get the volume of the stopper.

Answer 2

Answer:

• wash the density bottle and then dry it in hot air. Insert the stopper and find its mass on a physical balance

•Fill the density bottle with distilled water and then insert the glass stopper. Wipe the bottle from outside and again find its mass

•Pour off the water from the density bottle and dry it in hot air. Fill the bottle with liquid and insert the stopper and do the same process

Explanation:

Mass of empty bottle=m1g

Mass of empty bottle+water=m2g

Mass of empty bottle+Any liquid =m3g

«»Mass of only water=(m2-m1)g

Now, 1g of water = 1cm³

volume of water =(m2-m1)cm3

volume of bottle =(m2-m1)cm3

volume of liquid = volume of water=(m2-m1)cm³

also mass of only liquid=(m3-m1)g

density of liquid = mass of liquid / volume of liquid = (m3-m1)/(m2-m1) g/cm³
