Moles of water atoms = mass/molecular weight = 105/18 = 5.83 mol. Number of moles of hydrogen in water = 2 x moles of water = 11.66. Number of H atoms in water = moles of hydrogen x 6.02 x 10^23 = 7.019 x 10^24 ~ 7.02 x 10^24 atoms. Hope this helps.
First convert mL into liters:
1 L = 1000 mL
250 mL / 1000 = 0.25 L
M = n / V
M = 0.70 / 0.25
M = 2.8 mol/L⁻¹
hope this helps!
Na because its a metal. Metals are the best conductors. S and Ne are nonmetals. and Ge is a metalloid. (Metalloids are semi conductors)
