Question

The molecular massif co2 is 44. Find out the number of molecules in 220g co2

Answer 1

Answer:

30.11*10^23

Explanation:

MOLECULAR MASS OF CO2 IS 44 G mol^-1

given mass of CO2 = 220 g

no .  of moles = 220/44  =  5

no. of molecules in a mole = 6.022 * 10^23

no. of molecules in 5 mole = 5* 6.022 * 10^23 = 30.11*10^23

Answer 2

Explanation:

solution:-

•mass of co2 =220g

•molecular mass of co2=44

$number \: of \: moles = \frac{mass \: of \: co2}{molecular \: mass \: of \: co2}$

$= \frac{220g}{44}$

=5

no of mole in 220 g of co2 is 5

1 mole=6.022×10²³molecule

no of molecule in 5 moles =5×6.022×10²³
