Be sure to answer all parts. How many moles of water contain each of the following number of molecules?
Report your answer using appropriate number of significant figures.
a. 9.52 x 1026 molecules
_____ mol
b. 7.81 x 1022 molecules
_____mol
c. 2.5 % 1023 molecules
_____ mol
Answer:
1.520
1.333
15.899
Explanation:
its very easy
N = n x No
No = avogadro's number = 6.02 x 10²³
n = mol
a. 9.52 x 10²⁶ : 6.02 x 10²³ = 1.58 x 10³ (3 sig figs)
b. 7.81 x 10²² : 6.02 x 10²³ = 1.30 x 10⁻¹ = 0.130 (3 sig figs)
c. 2.5 x 10²³ : 6.02 x 10²³ = 0.42 (2 sig figs)

Explanation:
What is the number of molecules of CO2 in 0.236 moles?
Answer:
mole of CO2 = 6.023*10^23 molecules.
3 moles of CO2 = 3*6.023*10^23 molecules
therefore, 3 moles of CO2 = 18069*10^20 molecules.
