Question

what mass of carbon dioxide will contain 3.011x10²³ molecules​

Answer 1

Explanation:

No of Moles = 6.023×10 power 23

3.023×10 power 23

= 0.5 mol

Mass = 0.5×GMWt = 0.5×44 = 22 g

Answer 2

Answer:

22 Grams of carbon dioxide will contain 3.011x10²³ molecules​

Explanation: So Basically 3.011x10²³ is 1/2 mole of CO2

Now, no. of moles = Given Weight/ Molar Mass (Molar Mass= Mass Of Carbon+2*Mass Of Oxygen)

We need to find Given Weight

1/2 = GW/44                                               (GW=Given Weight)

Given Weight = 44/2

Therefore,

                Given Weight = 22 grams
