You 6 moles of a substance which of the following statements is true?

a. you have six times the number of particles that are in 12 grams of carbon-12.
b. you have one third the number of particles that are in 12 grams of carbon-12.
c. you have the same number of particles as in 12 grams of carbon-12.
d. you have three times the number of particles that are in 12 grams of carbon-12.

A

Step-by-step explanation:

1)The mole is a unit of measure that contains as many elementary entities as in atoms of 12 grams of Carbon  (12 AMU). The Carbon mass is the reference.

2)We have to specify which particle we are using when dealing with mole unit:

particle, atoms, molecules, ions, electrons, etc.

3) So If I have 6 moles of a substance, I am going to have six times the number of particles that are in 12 grams of carbon-12.

hope it you

step-by-step explanation:

sin(7pi/6 - pi/3)  

= sin(7pi/6 - 2pi/6)  

= sin(5pi/6)  

= sin(pi - pi/6)  

= sin(pi/6)  

= 1/2  

sin 7pi/6 - sin pi/3  

= sin (pi + pi/6) - sin pi/3  

= -sin pi/6 - sin pi/3  

= -1/2 - sqrt(3)/2  

= -(1+sqrt(3))2

they go with it happens or they mite give a chance?
