Find the molecules in 32 grams of CH4

════════ ∘◦❁◦∘ ════════

════════════════════

Mass = 32grams

Name of atom = Methane (CH4)

Molar mass C = 12

Molar mass H = 1

════════════════════

molecules (mol?)

════════════════════

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

c. because step up transformer steps up the input voltage i.e increases the input voltage  

the number of turns are greater on the secondary side of step up transformer  

transformer does not handle dc current
