Answer: 8.1e+2 or 8.1E+2 (in the scientific notation mode), based on that the number given is 8.1 × 10².
Explanation
Scientific calculators use the letter e or E to show the numbers in scientific notation mode.
These are some examples of numbers that require scientific notation and how they are shown.
Number Scientific calculator display
6.022 × 10²³ 6.022 e+23
5 × 10 -12 5 E -12
So, understanding that your question is about number 8.1 × 10², the scientific calculator could show 8e+2.
Nevertheless, since 8 .1 × 10² is 810, not a long number, if the display is not in scientific notation mode, it could just display just 810,
It has a fixed mass
it does not change with the shape of the container
it cannot be compressed
it has fixed atom and molecules and limited to very small displacement
only vibrational motion occur in the molecules of solid .
Answer: i think its protons and electrons but it also might just be atoms because protons and electrons make atoms when there are also neutrons
Explanation:
Answer:
54g
Explanation:
Given parameters:
Number of moles of H₂O = 3 moles
Unknown:
mass of water = ?
Solution:
To solve this problem, we use the expression below:
mass = number of moles x molar mass
Molar mass of H₂O = 2(1) + 16 = 18g/mol
Mass of water = 3 x 18 = 54g
The Ideal Gas Equation
The term pVnRT is also called the compression factor and is a measure of the ideality of the gas. An ideal gas will always equal 1 when plugged into this equation……
