A chemist prepares a solution of iron bromide by measuring out 59.5 mg of FeBr2 into a 100 mL volumetric flask and filling to the mark with distilled water.

Calculate the molarity of Br- anions in the chemist's solution.

How many molecules are in 6.0 moles of methane

Which factor is likely to impact the possible number of compounds ?

For the reaction shown, calculate how many moles of no2 form when each of the following completely reacts. 2n2o5(g)→4no2(g)+o2(g) part a 1.0 mol n2o5 express your answer using two significant figures. nothing mol m o l request answer part b 5.4 mol n2o5 express your answer using two significant figures.
