Answer:
The answer to your question is 80.3%
Explanation:
Data
Percent by mass of F
molecules NF₃
Process
1.- Calculate the molar mass of nitrogen trifluoride
molar mass = (1 x 14) + (19 x 3)
= 14 + 57
= 71 g
2.- Use proportions and cross multiplications to find the percent by mass of F. The molar mass of NF₃ is equal to 100%.
71 g of NF₃ ------------------ 100%
57 g of F ------------------- x
x = (57 x 100)/71
x = 5700 / 71
x = 80.3%
3.- Conclusion
Fluorine is 80.3% by mass of the molecule NF₃
(B), because 1.0 moles would be 6.02 x 10^23 molecules. So you have half a mole.<span>

You convert kinetic energy into thermal energy when you rub two sticks together.
The answer is likely to be A
Answer:
The material that would most likely slow the flow of electricity is plastic.
Explanation:
Plastic is a conductor. A conductor is something that stop or slows down the flow of electricity.
