Answer:
63.55
Explanation:
relative atomic mass=(mass of isotope1×relative abundance)+(mass of isotope 2×relative abundance)/100
r.a.m=(62.93×69.09)+(64.93×30.91)/100
=(4347.8337)+(2006.9863)/100
=6354.82/100
=63.55

Explanation:
the moon is still volcanic
Answer:
ust use the equation
M1 X V1 = M2 X V2
where M1 is the initial concentration, V1 the volume of M1, M2 the final concentration and V2 the final volume. Here you are looking for V1 so, first solve for V1 and put in the numbers.
V1 = (M2 X V2)/M1 = (3 X 0.5)/18 = 0.5/6 = 0.083 L or 83 mL
