Question

Density of aluminum is 2700kg/m^3 and that of steel is 5800kg/m^3. Calculate the mass of steel having same volume as 1350kg of aluminium.
​

Answer 1

Answer:

Here's your answer

Explanation:

p=Z×Ma3×N0ora3=Z×Mp×N0=4×0.027kgmol−12700kg m−3×6.02×1023 mol−1

=66.4×10−30m3ora=(66.4)1/3×10−10m

Putting (66.4)1/3=x,

logx=13log66.4=1.82223=0.6074

∴x=4.050,∴a=4.05×10−10 m

for fcc , r=a22–√=4.05×10−10m2×1.414=1.43×1010m
