Calculation of Moles of N2O left after removing 10^20 molecules from 50 mg of N2O
Given:
- Amount of N2O = 50 mg
- Number of molecules removed = 10^20
Calculations:
1. Find the number of moles of N2O initially present:
- Molar mass of N2O = 28 g/mol
- Number of moles of N2O = (50 mg / 1000 mg/g) / (28 g/mol) = 0.001786 moles
2. Find the total number of molecules present initially:
- Avogadro's number (NA) = 6.022 x 10^23 molecules/mol
- Number of molecules of N2O = 0.001786 moles x 6.022 x 10^23 molecules/mol = 1.076 x 10^21 molecules
3. Find the number of molecules left after removing 10^20 molecules:
- Number of molecules of N2O left = 1.076 x 10^21 molecules - 10^20 molecules = 9.76 x 10^20 molecules
4. Find the number of moles of N2O left:
- Number of moles of N2O left = 9.76 x 10^20 molecules / 6.022 x 10^23 molecules/mol = 0.162 moles
Answer:
The number of moles of N2O left after removing 10^20 molecules from 50 mg of N2O is approximately 0.162 moles.
