First convert 1.26g to moles:
1.26g *(mole/169.87g) = 0.007417mol
Remember that molarity is the same as mole/L:
0.007417mol *(1/250mL) * (1000mL/L) = 0.02966M
Answer:
12408 feet per minute
Explanation:
Given: Speed is 141 mi/h
To find: speed in units of feet per minute
Solution:
Use the following units to convert the given speed into feet per minute.
1 mile = 5280 foot
1 h = 60 minutes
Therefore,
141 mi/h feet per minute.
This means that the mass of one mole of aluminium atoms will be 26.982 g . As you know, one mole of any element contains exactly 6.022⋅1023 atoms of that element.
The 5 rotational levels would there be between the ground vibrational state and the first excited vibrational state.
What is rotational levels?
The three major moments of inertia IA, IB, and IC determine the rotational energy levels for a nonlinear molecule. They revolve around three axes that are mutually orthogonal to one another and have their origin (or intersection) at the molecule's Centre of mass.
What is vibrational state?
The rotation of the molecule brought on by various vibrations in perpendicular planes is described by (123) or (12l23), where 0 l2 2 is an angular momentum quantum number.
Therefore , 5 rotational levels would there be between the ground vibrational state and the first excited vibrational state.
