The densities of calcium (ca ) and b...

The densities of calcium (ca ) and barium (Ba ) are 1.55 and 3.51 g `cm ^(-3) ` respectively based on Dobereiner's law of triads , can you give the approximate density of strotium (Sr ) ?

Text Solution

Verified by Experts

Density of `Ca= 1.55 gm cm^(-3 )`
Density of Ba `=3.51 gm cm ^(-3) `
Average density `=(1.55+3.51)/(2)=2.53`
The density of `Sr = 2.64 ` M
Average density of Ca and Ba is approximately equal to the density of Sr.
