Answer:
4.55 * 10^23 molecules
Explanation:
This is a conversion problem. We know that one mole has 6.022 *10^23 particles or molecules so we can use this as a conversion factor.
0.755 mol ( 6.022*10^23 molecules/ 1 mol)
=4.55*10^23 molecules
Answer:
93 moles
Explanation:
1 mole of CaCO_3 will have 6.022×10^(23) molecules of CaCO_3 .
Given number of molecules of Calcium carbonate = 5.60 x 10^(25)
Therefore, number of moles n =
n= 93 moles
Answer:
The partial pressure of chlorine gas in the mixture is 1.55 atm.
Explanation:
Partial pressure of oxygen gas =
Partial pressure of nitrogen gas =
Partial pressure of chlorine gas =
Total pressure of the mixture of gases = P = 3.30 atm
Using Dalton's law of partial pressure:
The partial pressure of chlorine gas in the mixture is 1.55 atm.
