Answer:
13.5
Step-by-step explanation:
2/3=9/x
2x=9*3
2x=27
x=27÷2
x=13.5
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.
Triangles add to 180° and there is already 100° shown inside of the triangle (30° plus 70° = 100°). 180° -100° = 80°, which is x. X and y are vertical angles, so y is also 80°. The answer is B.
