11.82 x 1 mole / (molar mass)
The molar mass = 197 g/mol
11.82 / 197 = .06

Answer:
The answer to your question is 0.13 M
Explanation:
Data
[HNO₃] = ?
moles of HNO₃ = 9.8 x 10⁻²
volume = 705 ml
Process
1.- Convert volume to milliliters
1000 ml ------------------ 1 L
705 ml ------------------ x
x = (705 x 1) / 1000
x = 705 / 1000
x = 0.75 L
2.- Calculate the molarity
Molarity = moles / volume
Molarity = 9.8 x 10⁻² / 0.75
Molarity = 0.13
Hydrogen and helium because they only have one electron shell and it only holds up to two electrons in it.
