Answer

The weighted average atomic mass of chromium is 52.00 u.

Work Step by Step

The weighted average atomic mass of chromium can be calculated by adding the product of each isotope's mass and its natural abundance and dividing by the total abundance: (49.9461 u x 0.0435) + (51.9405 u x 0.8379) + (52.9407 u x 0.0950) + (53.9389 u x 0.0236) = 52.00 u Therefore, the weighted average atomic mass of chromium is 52.00 u.
