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.
If you add the numbers 57 and 59 together you get 116
Answer:
16
Step-by-step explanation:
The differnce of 28 and 12 is 16 because, 28-12=16 and 16+12=28
9/2 is the simplest form of 18/4.
Hope that helps.
