The other given data are:
<span>Room temperature (°C) 22.0; pressure (kPa) 100.5; Water vapor pressure at 22 °C (2.60 kPa); Mass of Mg ribbon (0.05g); Volume of hydrogen gas (mL) 48.3
</span>
<span>Vstp = 22.4 L/mol, and Vsatp = 24.8 L/mol Vstp:0 degrees Celsius and 101.325 kPa while Vsatp: 25 degrees Celsius and 100 kPa. 100.5 kPa x 760 mm Hg/101.325 kP = 753.8119911 mmHg
</span><span>2HCl(g) + Mg(s) -> H2(g) + MgCl2(aq) nMg = 0.0020571899 mol nH2 = 0.0020571899 mol Wet H2 pressure = 100.5 kPa Dry H2 pressure = 97.9 kPa
</span><span>
So to determine the volume of hydrogen gas collected at STP: V2 = (753.8119911 mmHg)(48.3 mL)(273 K) / (295 K)(760 mmHg) = 44.33403003 mL.
</span>
<span>Molar volume at STP: mol/L = 44.33403003 mL / 0.0020571899 mol
= 21550.77176 mL/mol
= 21.55077176 L/mol
To determine volume of hydrogen gas collected at SATP:
V2 = (100.5 kPa)(48.3 mL)(298 K) / (295K)(100kPa) = 49.03514237 mL
Molar volume at SATP: mol/L = 49.03514237 mL / 0.0020571899 mol
= 23835.98246 mL/mol
= 23.8359824 L/mol</span>
Answer:
Sodium chloride (Table Salt)
Explanation:
When two or more elements combine with or without the application of heat, a compound is formed. Any compound in which the elements have a complete gain and loss of electron is termed as ionic compound.
Ionic compounds have the excellent property of dissolving in water. They form ions, both positively charged and negatively charged, which conduct electricity in aqueous medium and therefore can be called as electrolytes.
Sodium chloride (Table Salt) is a common example of ionic compound. It dissolves in water. It is an electrolyte and it is an excellent conductor of electricity. So, the best choice would be Sodium chloride.
