Answer:
The mass of the isotope Chromium-50 would be 2.685 grams in 61.8 grams of elemental Chromium.
Explanation:
Natural chromium () is composed of four stable isotopes:
(4.345 % abundance),
(83.789 % abundance),
(9.501 % abundance) and
(2.365 % abundance). We can obtained the total mass of the isotope Chromium-50 (
), measured in grams, by multiplying the mass of elemental chromium (
), measured in grams by percentage ratio (
), dimensionless. That is:
If we know that and
, then the mass of isotope Chromium-50 would be:
The mass of the isotope Chromium-50 would be 2.685 grams in 61.8 grams of elemental Chromium.
