Step-by-step explanation:
What is the molar mass of an element?
the total number of particles in one gram of the element
the mass of 6.02 x 1023 representative particles of the element
the number of amus (atomic mass units) in 6.02 x 1023 moles of the element
1.0 gram divided by the atomic weight of the element
Using the Law of Cosines:
d= √(840^2 + 800^2 - 2*840*800*cos(105))
d = √1693452.796
d = 1301 miles.
The answer is B.
Answer: 7x + 70
Step-by-step explanation:
Answer:
For part a you need to factor. X to the power of 2 is 2x. when you add it its turns into 2x+10x+16=0
