Question

What is the mass of oxygen in 88 g of carbpn dioxide?

Answer 1

Answer:

Hola Mate....

• Molar Mass of co2=44

• Now there are 2 atoms of O2 in 1 mole Co2.
• Moles of CO2 = Mass ÷Molar mass
• 88÷44==>>2Moles
• Now mass of O2 in 1 mole CO2 = 2×16 g =>> 32 g
• Mass of O2 in 2 moles CO2=

2×32

==>>

64 grams
