Calculate the number of mokes in 3.011×10223.011×1022 moles of carbo

1.	Calculate the number of mokes in 3.011×10223.011×1022 moles of carbon dioxide
Answer» Answer:If mass is GIVEN, mole = given mass/molar/atomic mass If volume is given at STP/NTP, mole = given volume (in L)/22.4 L If the no of atoms/molecules is given, mole = no of atoms/molecules/Avogadro's number Now see your QUESTIONS once again, here no of molecules of carbon dioxide is given, so we have to APPLY last one. I.e., mole = no of molecules/Avogadro's number Here no of molecules = 3.011 × 10²² Avogadro's number = 6.022 × 10²³ So, mole = 3.011 × 10²²/6.022 × 10²³ = 1/20 = 0.05 Therefore the no of moles is 0.05 of carbon dioxide.

Calculate the number of mokes in 3.011×10223.011×1022 moles of carbon dioxide

Answer»

Answer:If mass is GIVEN,

mole = given mass/molar/atomic mass

If volume is given at STP/NTP,

mole = given volume (in L)/22.4 L

If the no of atoms/molecules is given,

mole = no of atoms/molecules/Avogadro's number

Now see your QUESTIONS once again, here no of molecules of carbon dioxide is given, so we have to APPLY last one.

I.e., mole = no of molecules/Avogadro's number

Here no of molecules = 3.011 × 10²²

Avogadro's number = 6.022 × 10²³

So, mole = 3.011 × 10²²/6.022 × 10²³

= 1/20

= 0.05

Therefore the no of moles is 0.05 of carbon dioxide.
