Answer:
The new volume reading for the graduated cylinder is :
<u>35 mL</u>
Explanation:
If a graduated cylinder has 32.0 mL of water in it. A 3.0 cm3 rock is dropped into the graduated cylinder. The new volume reading for the graduated cylinder is :
Here , Volume of rock is given : 3 cm3
<u><em>1. Do unit conversion first</em></u>
.........(1)
1 dm = 10 cm
.........(2)
Also.
1 L = 1000 mL........(3)
Insert the value of L and dm3 in equation (1)
1000 cancel each other
So,
2. Find the total volume
Volume of rock = 3 mL
Volume of water = 32 mL
New volume =Volume of rock + Volume of water
New volume = 3 mL + 32 mL
<u>New volume = 35 mL</u>
<em>What is need of unit conversion ?</em>
<u><em>Because Only those quantities can be added or subtracted which have same units </em></u>
