The volume that would be necessary to decrease the pressure to 1.0 atm is mathematically given as

v2=6.4l

<h3>What volume would be necessary to decrease the pressure to 1.0 atm?</h3>

Question Parameter(s):

A 2.0 l container of oxygen had a pressure of 3.2 atm

Generally, the equation for the   is mathematically given as

P1v1=p2v2

Therefore

v2=piv1/p2

v2=2*3.2/1

v2=6.4l

In conclusion, the  volume is

v2=6.4l

12.1 g CoCl3 calculate the amount, in moles
elena-s [515]

Answer:

Number of moles of CoCl3 =  0.09 moles

Explanation:

Given data:

Mass of CoCl₃ = 12.1 g

Number of moles = ?

Solution:

First of all we will calculate the molar mass.

Molar mass of CoCl3 = 28.01 + (35.5×3)

Molar mass of CoCl3 = 28.01 + 106.5

Molar mass of CoCl3 = 134.51 g/mol

Number of moles of CoCl3 = mass / molar mass

Number of moles of CoCl3 = 12.1 g/134.51 g/mol

Number of moles of CoCl3 =  0.09 moles

The green light emitted by a stoplight has a wavelength of 525 nm. What is the frequency of this photon? (c = 3.00 × 10⁸ m/s).
Reil [10]

The frequency of this photon is 5.94 x 10^{14} H_{Z}.

Solution:

The speed of light has a value of approximately <u>3.00×108 m/s</u>

The wavelength should have units of meters.

The frequency should have units of Hz or s−1. Hz is hertz or reciprocal seconds.

We know the value of the speed of light and we are given the wavelength. All we have to do is rearrange the equation to solve for the frequency:

<u>v = c/λ</u>

= 3.00×10^{8} m/s/505×10^{-9} m

= 5.94X10^{14}s-1

= <u>5.94X</u>10^{14}<u> Hz</u>

<u />

Frequency describes the number of waves passing through a particular location at a particular time. A class interval frequency is the number of observations that occur in a particular predefined interval. So, for example, if 20 of her ages 5-9 appear in the survey's data, the interval 5-9 has a frequency of 20. The class interval endpoints are the lowest and highest possible values ​​of the variable.
