Answer:
D. Displacement and distance traveled are the same if the direction does not change.
Answer:
4.87×10²⁴ molecules
Explanation:
Given data:
Mass of glucose = 1456 g
Number of molecules = ?
Solution:
Number of moles of glucose:
Number of moles = mass/molar mass
Number of moles = 1456 g/ 180.156 g/mol
Number of moles = 8.1 mol
1 mole of glucose contain 6.022×10²³ molecules
8.1 mol × 6.022×10²³ molecules / 1 mol
48.7×10²³ molecules
4.87×10²⁴ molecules
Answer:
<h2>The answer is option C</h2>
Explanation:
The percentage error of a certain measurement can be found by using the formula
From the question
actual density = 0.1478 g/mL
error = 0.1478 - 0.1369 = 0.0109
The percentage error is
We have the final answer as
<h3>7.375 %</h3>
Hope this helps you
Explanation:
Following are the kinetic theory of gases postulates:
1) Space-volume to molecules ratio is negligible.
2)There is no force of attraction between the molecules at normal temperature and pressure. The force of attraction between the molecules build when the temperature decreases and the pressure increases.
3) There is large space between the molecules resulting in continuous motion.
4) The free movement of molecules results in collision which is perfectly elastic.
5) The molecules have kinetic energy due to random movement. But the average kinetic energy of these molecules differs with temperature.
6) Molecules exert pressure on the walls of the container.
