.1) A fictitious element X is composed of 20 percent of the isotope X-50, 15 percent of the isotope X-51, and 65 percent of the isotope X-52. Calculate the relative atomic mass of element X. * 2)Calculate the relative atomic mass of silicon if the three silicon isotopes have mass and relative abundances of 27.9769 (92.2297%), 28.9765 (4.6832%) and 29.9738 (3.0872%). *

hi my dude or dudette

every chemical equation adheres to the law of conservation of mass, which states that matter cannot be created or destroyed. therefore, there must be the same number of atoms of each element on each side of a chemical equation.

the cold front replaces the warmer air at the ground level changing the wind to be breezy and denser.there is also an immediate drop in the temperature.

i think its 100

i hope this !
