Answer 1

3 biven, 19.32 g of bold lo lomo of volume. density of gold, d = 19.32 3 = 19.32 g 1 cm V 1 Now, mass of block of gold, m = 26.73 g volume of leaf = Area of leaf a thickness A x 1.345 x 10-4 cm?

NOW, volume of Leaf -4 A X 1.345810 Mass density 26.73 19.32 = 1.383 A - 1.383 1.345 110 4 = 1.028 X10 4 2 А cm2 A 1.028 mi n2 2 Area of leaf , A = 1.028 m
