Both acids are strong, so the concentration of H+ ions will be the same as the concentration of the acid(s). Supposing additive volumes: ((4.526 L x 0.3521 M) + (5.275 L x 1.563 M)) / (4.526 L + 5.275 L) = 1.004 M

No, they do not have the same conductivity. The reason is that KI is a strong electrolyte, i.e. it ionizes completely. However HF is a weak electrolyte, i.e. it ionizes only partially.

the molar mass of methane (CH4) is 16 g. (C=12 and H=1). So, 1.6 g of methane is 0.1 mole of methane. How many electrons in CH4? C has 6 and each H has 1, so each molecule of CH4 has 10...

a milliliter is also one cubic cm. You have 1000 of those units. Multiply the density by 1000 to get the mass.
