A 1960 silver quarter is found to have a mass of 6.25 grams. On a given day, the value of silver is $17.32 per ounce. How much is this coin worth if the coin is 92% silver?

Solutions

Expert Solution

Ans. Mass of pure silver = 92% of mass of coin

                                    = 92% of 6.25 g

                                    = 0.92 x 6.25 g

                                    = 5.75 g                                                          ; [1 g = 0.2028253 oz]

                                    = 5.75 x (0.035274 oz)

                                    = 0.2028253 oz

# Value of solver coin = Rate of silver x Mass of solver in coin

                                    = ($17.32 / oz) x 0.2028253 oz

                                    = $3.513

Hence, value of silver coin = $3.513
