Use the References to access important values if needed for this question. A sample of a substance with the empirical formula XBr3 weighs 0.5411 9. When it is dissolved in water and all its bromine is converted to insoluble AgBr by addition of an excess of silver nitrate, the mass of the resulting AgBr is found to be 1.0451g. The chemical reaction is XBr3+3AgNO33AgBr+X(NO3)3 (a) Calculate the formula mass of XBr3. FormulamassXBr3=gmolm1 (b) Caiculate the atomic mass of X. Atomicmassx=gmol1
