when 68.00 j of energy are added to a sample of gallium that is initially at 25 oc, the temperature rises to 38.0 oc. what is the volume of the sample in cm3? specific heat of gallium

Respuesta :

The volume of sample in cm3 is   (0.515 g) / (5.91 g/cm^3)

How to estimate volume of the sample in cm3?

Volume is a three-dimensional measurement that's used to gauge a solid shape's capacity. It implies that the volume of a closed figure determines how much space it can occupy in three dimensions.

With the input of 68 J of energy, the temperature rises by 13 K, and the molar heat capacity of gallium is 25.86 J/(mol*K)  

68 J * 25.86 J/(mol·K) * x mol=13 K

x=13/(68*25.86)=0.00739 mol  

Molar mass of gallium is 69.723 g/mol, making the mass of this sample 0.515 g of gallium:

0.151 g = 68.723 g/mol * 0.00739 mol  

The gallium's density is 5.91 g/cm^3, making the volume of this sample

0.872 cm^3 of gallium:

0.872 cm^3 = (0.515 g) / (5.91 g/cm^3)

Therefore the volume of sample cm3 is  (0.515 g) / (5.91 g/cm^3)
