Answer:

The mass of the isotope Chromium-50 would be 2.685 grams in 61.8 grams of elemental Chromium.

Explanation:

Natural chromium ( $Cr$ ) is composed of four stable isotopes: $^{50} Cr$ (4.345 % abundance), $^{52}Cr$ (83.789 % abundance), $^{53}Cr$ (9.501 % abundance) and $^{54}Cr$ (2.365 % abundance). We can obtained the total mass of the isotope Chromium-50 ( $m_{^{50}Cr}$ ), measured in grams, by multiplying the mass of elemental chromium ( $m_{Cr}$ ), measured in grams by percentage ratio ( $r$ ), dimensionless. That is:
