A 2.16-g sample of an oxide of chromium contains 1.34 g of chromium. Calculate the simplest formula for the compound.
fomenos

Answer:

chromium:oxygen=1:2  

Explanation:

total mass=2.16g

mass of chromium=1.34g

mass of oxygen=2.16g-1.34g=0.82g

           chromium                                         oxygen

mass:1.34g                                                       0.82

RAM:52                                                            16

divide the mass with the RAM

   0.02577                                                           0.05125

divide by smallest number to find ratio

1                                                                             2

ratio of chromium to oxygen=1:2
