A solid having density of ` 9 xx 10 ^3` forms face centerd cubic crystals of edge leght `200 sqrt(2)) Pm.`What is the molar mass of the solid ? [Avogadro castant `cong 6 xx 10 ^(23) mol ^(-1) , pi cong 3`]
A solid having density of 9 xx 10^(3) kg m^(-3) forms face centred cubic crystals of edge length 200 sqrt2 pm. What is the molar mass of the solid ? [Avogadro constant ~= 6 xx 10^(23) mol^(-1), pi ~= 3 ]
A substance has a face centred cubic crystal with a density 1.984 g cm^(-3) and edge length 630 pm. Calculate the molar mass of the substance
An element with density 2.8 cm^(3) forms a f.c.c unit cell with edge length 4xx10^(-8) cm. calculate the molar mass of the element. Given: (N_(A)=6.022xx10^(23)) mol^(-1)
A metal has an fcc latticed.The edge length of the unit cell is 404 pm .The density of the metal is 2.72 g//cm^(-3) .The molar mass of the metal is (N_(A) Avogadro's constant = 6.2 xx 10^(23) mol^(-1))
