If one atom of hydrogen weighs 1.65 xx 10^(-24)g, then mass of one atom of carbon weighs

Answer»

`1.98 xx 10^(-23) g `
`1.65 xx 10^(-24) g `
`1.37 xx 10^(-25) g `
`1.40 xx 10^(-23) g `

Solution :An atom of carbon is 12 times HEAVIER than an atom of HYDROGEN . THEREFORE , mass of one atom of carbon ` = 1.65 xx 10^(-24) xx 12 = 1.98 xx 10^(-23) g `
