How many times (roughly) is the resistivity of an insulator greater than a metal ?

The equivalent weight of a metal is double than that of oxygen. How many times in the weight of its oxide greater than the weight of metal ?

The equivalent mass of a metal is twice to that of oxygen. How many times the weight of it's oxide is greater than the weight of metal?

Choose the correct alternatives : (a) Alloys of metals usually have (greater/less) resistivity than that of their constituent metals. (b) Alloys usually have much (lower/higher) temperature coefficients of resistance than pure metals. (c ) The resistivity of the alloy manganin in (nearly independent of/ increase rapidly ) with increase of temperature. (d) The resistivity of a typical insulator (e.g. amber) is greater than that of a metal by a factor of the order of (10^(22) or 10^(3)) .

Choose the correct alternative: The resistivity of a typical insulator (e.g. amber) is greater than that of a metal by a factor of the order of ( 10^(22) / 10^3 )
