Suppose you have 61.8 grams of elemental chromium. How many grams would be the isotope chromium - 50?

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.
