Question

Calculate no. of moles of oxygen present in 22g of co2

Answer 1

mass of co2 : 12 + 16*2 = 12+32 = 44u
given mass = 22g

no. of moles of co2 = given mass / molar mass = 22 / 44 = 0.5 moles

Now in CO2
1 C atom and 2 oxygen atoms
so 1 mole of CO2 has 1mole of carbon and 2 moles of oxygen

thus in 0.5 moles there are 2 / 2 = 1 mole of oxygen in 22g (0.5 moles) of CO2.

Answer 2

Answer:

Step-by-step explanation:

If there is half as a power with any no. Such as - 49½

Then it becomes √49

that is = 7.

Or suppose there is 64⅓

Then = ³√64

= 4
