The answer of the question is C. Magnetic fields
Answer:
2.24 g
Explanation:
First we use the<em> PV=nRT</em> formula to <u>calculate the number of moles of the gas</u>:
- 0.957 atm * 1.30 L = n * 0.082 atm·L·mol⁻¹·K⁻¹ * 298 K
Then we can use the<em> given molar mass</em> to <u>calculate the mass</u>:
- Molar Mass = Mass / number of moles
- 44.01 g/mol = Mass / 0.0509 mol
