Step-by-step explanation:
1 mole of any substance = 6.022 * 10²³ molecules.
Number of moles of CO2
= (4.5 * 10¹⁶)/(6.022 * 10²³)
= 0.75 * 10^(-7)
= 7.5 * 10^(-8) mol.
I hope this helps with you
You subtract 16 from each side of the equation.
Then it will say exactly what number 'n' is.
_______________________________________
The equation is n + 16 = 9
On the left side, you subtract 16 from (n + 16) and you have 'n'.
On the right side, you subtract 16 from 9 and you have -7 .
Now the equation says n = -7
Once you combine like terms you are left with 18k +3.
Answer:
from that passage AB+BD=AD ; -4x+50+2x+4=2x+46 so -2x+54=2x+46 ; x=2.
AC=AB+BC ; AB=-4x+50=-4(2)+50=42
the total lengths is AD=2x+46=50
Therefore AC is more than 42 and less than 50 ; you can answer b,c,g
