POH=4.22
pOH = -lg[OH⁻]
[OH⁻]=10^(-pOH)
[OH⁻]=10⁻⁴·²² = 6.0×10⁻⁵ mol/L
6.0×10⁻⁵ M
Answer:
Average atomic mass = 24.3051 amu
Explanation:
Average Atomic Mass = (Mass of Isotope 1 x Fractional Abundance of Isotope 1) + (Mass of Isotope 2 x Fractional Abundance of Isotope 2) + ......
For 24 Mg
Mass = 23.985 amu
Fractional Abundance = 0.7899
Mass * Fractional Abundance = 18.9458
For 25 Mg
Mass = 24.986 amu
Fractional Abundance = 0.10
Mass * Fractional Abundance = 2.4986
For 26 Mg
Mass = 25.983
Fractional Abundance = 0.1101
Mass * Fractional Abundance = 2.8607
Average atomic mass = 24 Mg + 25 Mg + 26 Mg
Average atomic mass = 18.9458 + 2.4986 + 2.8607
Average atomic mass = 24.3051 amu
