Explanation:
Oil is less dense than water or most liquids found in Saldana dressing, so the denser liquid sinks to the bottom, leaving the oil on top. It's same principle on how a helium balloon floats in air, the helium is less density than the air around it.
Answer:
1 mol of any compound (including of course CO2 and O2) contains 6.022*10^23 molecules
Therefore 0.5 mol of CO2 and O2 contains 3.01*10^23 molecules of each.

A scooter is moving with a speed of 18 m/s. Its mass is 20 kg. What is the magnitude of its momentum?
A. 360 kg.m/s
B. 2 kg.m/s
C. 3600 kg.m/s
D. 1.1 kg.m/s
<h2><u>A</u><u>n</u><u>s</u><u>w</u><u>e</u><u>r</u>:-</h2>
<h3>Given:-</h3>
Speed (v) of a scooter = 18 m/s
Mass (m) = 20 kg
<h3>To Find:-</h3>
Magnitude of its momentum (p) = ?
<h3>Answer:-</h3>
Since, we know that,
p = mv
So,
p = 20 kg × 18 m/s
p = 360 kg.m/s
<h3>

The correct option is (A) 360 kg.m/s </h3>
<h3>The magnitude of its momentum is <u>3</u><u>6</u><u>0</u><u> </u><u>k</u><u>g</u><u>.</u><u>m</u><u>/</u><u>s</u>. [Answer]</h3>
