Answer:
On the placement of hydrogen and helium in the periodic system
H1=1
He2=2
In
this case, we can simply use a ruler to measure the heights of the signal. Use the
same ruler all throughout to reduce deviations in the measurement.
So
for example we have 3 isotopes, so we get 3 signals with heights of (for
example):
isotope
1 = 62
isotope
2 = 2
isotope
3 = 8
Therefore
the mass of the signals would be:
62
+ 2 + 8 = 72
The
fractional abundance of each isotope would be:
frac
isotope 1 = 62/72 = 0.86
frac
isotope 2 = 2/72 = 0.03
<span>frac
isotope 3 = 8/72 = 0.11</span>
Answer:
The Density Calculator uses the formula p=m/V, or density (p) is equal to mass (m) divided by volume (V). The calculator can use any two of the values to calculate the third. Density is defined as mass per unit volume.
