請問鉍元素(bismuth) , 重量大概是多少?

又有人答非所問

let density of bismuth metal: 9.8 g/cm^3
the dimension of the crystal in inches: 1.5 x 1.375 x 0.875 inch^3
the volume of the crystal in cm^3: 1.5 x 1.375 x 0.875 x (2.54)^3 = 29.5735 cm^3
the mass of the bismuth metal: 29.5735 x 9.8 = 289.82g

the conversion factor of cm: inch = 2.54:1

2.54:1
