Question

specific heat of metal is 0.30 and its chloride contains 83 percent of chlorine what is exact atomic weight of the material ​

Answer 1

Answer:

The mass of chlorine in metal chloride is given= 49.5%

Therefore the mass of metal= (100-49.5) = 50.5

The equalent mass of metal is given by the formula:

$massofmetal</p><p> </p><p> ×35.5</p><p> </p><p>49.5</p><p>50.5</p><p> </p><p> ×35.5=36.21</p><p>$

According to dulong pettits law:

Hence, 3.1g is the answer.The mass of chlorine in metal chloride is given= 49.5%

therefore the mass of metal= (100-49.5) = 50.5

The equivalent mass of metal is given by the formula:

$= </p><p>massofchlorine</p><p>massofmetal</p><p> </p><p> ×35.5</p><p></p><p> = </p><p>49.5</p><p>50.5</p><p> </p><p> ×35.5=36.21$

$According to dulong pettits law:</p><p></p><p> atomic mass of metal= </p><p>specificheat</p><p>6.4</p><p> </p><p> </p><p></p><p> = </p><p>0.056</p><p>6.4</p><p> </p><p> ×114.3</p><p></p><p> = </p><p>equivalentmass</p><p>atomicmass</p><p> </p><p> </p><p> </p><p> = </p><p>36.21</p><p>114.3</p><p> </p><p> =3.1g</p><p></p><p> Hence, 3.1g is the answer.$
