How many fluorine atoms are found in 1.92 grams of AsF3?

11111nata11111 [884]

First you need to find out how many moles of AsF3 are in 1.92 grams.
The molar mass of AsF3 is 131.918 g/mole so
1.92 g * (1 mole)/(131.918g) = .0146 moles AsF3

Each mole of AsF3 has 6.02 x10^23 molecules of AsF3 and each molecule of AsF3 has 3 flourines, so you need to convert from moles to molecules AsF3 to atoms of F
0.146 moles AsF3 * (6.02 x 10^23 molecules AsF3)/(1 mole AsF3) * (3 atoms F)/(1 molecule AsF3) = 2.64 x 10^22 atoms F

In a class of 125 students, 28 are computer science majors, 52 are mechanical engineering majors, 12 are civil engineers and the

Studentka2010 [4]

Answer:

The probability none mechanical engineering majors is 0.03967.

Step-by-step explanation:

Given that,

Total students = 125

Number of students in computer science = 28

Number of students in mechanical engineering = 52

Number of students in civil engineering= 12

Suppose six students from the class are chosen at random what is the probability none are mechanical engineering majors?

We need to calculate the probability none are mechanical engineering majors

Using given data

None mechanical engineering majors = $\dfrac{125-52}{125}=0.584$

If six students from the class are chosen at random then

The probability none are mechanical engineering majors will be

$P_{nme}=(0.584)^6$

$P_{nme}=0.03967$

Hence, The probability none mechanical engineering majors is 0.03967.
