<h3>Answer = 2</h3>
════════════════════
<h3>Known</h3>
Mass = 32grams
Name of atom = Methane (CH4)
Molar mass C = 12
Molar mass H = 1
════════════════════
<h3>Question</h3>
molecules (mol?)
════════════════════
<h3>Way to do</h3>
mass = mol × molar mass
32g = mol × (CH4)
33g = mol × (12 + (4×1))
32g = mol × 16
mol = 32 : 16
mol = 2
════════════════════
#Ey tell me if its mol or total particles
M=7M(H₂O)
M=7*18.015 g/mol = 126.105 g/mol
So basically Positive reinforcement is when you give someone something for showing a good behavior, and a negative reinforcement is giving someone a consequence for showing bad behavior.
Hope this helps:)
