Final answer:
Approximately 114,817.15 coulombs of positive charge are present in 1.19 mol of neutral molecular hydrogen gas (H2), calculated by multiplying the charge of one mole of protons by the number of moles of hydrogen gas.
Step-by-step explanation:
Calculating Coulombs of Positive Charge in Hydrogen Gas
To determine the amount of positive charge in 1.19 mol of neutral molecular hydrogen gas (H2), we need to calculate the charge carried by the protons in one mole of hydrogen molecules. A neutral hydrogen molecule has two hydrogen atoms, each with one proton. Since the charge of one proton is +1.602 × 10-19 C, and one mole of any substance contains Avogadro's number of particles, which is approximately 6.02 × 1023, we can find the total positive charge in moles of hydrogen gas.
Step 1: Calculate the charge of one mole of protons (single positive charges).
Step 2: Multiply the charge per mole by the number of moles.
Thus, 1.19 mol of neutral molecular hydrogen gas contains approximately 114,817.15 coulombs of positive charge.
