4.5 g of alloy contains 3.5 gm
so 1 gm of an alloy will contain 3.5/4.5 gm of copper=7/9 gm of copper
so 18.9 gm of alloy will contain (7/9)*18.9 gm of copper =14.7 gm of copper.
so 1 gm of an alloy will contain 3.5/4.5 gm of copper=7/9 gm of copper
so 18.9 gm of alloy will contain (7/9)*18.9 gm of copper =14.7 gm of copper.
