How many moles are in a 61 g sample of zinc fluoride, ZnF₂?  

You MUST show all work starting with the calculation of molar mass, followed by the formula with variables from the VVS course (and rearrangement if needed) to determine moles, then the substitution of values into the formula, then the calculated answer.  You then need to remember to include units and use correct significant digits in your final answer.  Responses only showing the final answer will receive a zero grade.

Note, to show division please use the "slash" symbol on your keyboard under the question mark.  

For example, 4/8 = 0.5
