Question

the number of moles present in 3.011 * 10^25 molecules of co2

Answer 1

Answer:

We know, 1 mol of any substance contains 6.022 × 10²³ no of particles. 6.022×10²³ atoms are present in 1 mol of oxygen. 1 atom is present in 1÷6.022×10²³ mol of oxygen. 3.011×10²³ atoms are present in (1÷6.022×10²³) × 3.011×10²³ mol of oxygen.

Answer 2

Answer:

22 g

Explanation:

No of Moles =

6.023×10

23

3.023×10

23

= 0.5 mol

Mass = 0.5×GMWt = 0.5×44 = 22 g
