Answer:

0.131 mol

Explanation:

To convert grams to moles, you need to use the molar mass.  The molar mass is the mass number.  You can find this on the periodic table.  The molar mass of sodium is 22.990 g/mol.

(3.02 g)/(22.990 g/mol) = 0.131 mol

How much heat in joules is required to heat a 43g sample of aluminum from an initial temperature of 72˚F to a final temperature
Stels [109]
The first step to answering this item is to convert the given temperatures in °F to °C through the equation,

   °C = (°F - 32)(5/9)

initial temperature: 72°F

    °C = (72 - 32)(5/9) = 22.22°C

final temperature: 145°F
   
    °C = (145 - 32)(5/9) = 62.78°C

Substituting to the equation,

    H = mcpdT
    
    H = (43 g)(0.903 J/g°C)(62.78 - 22.22)
   
   H = 1574.82 J

<em>Answer: 1574.82 J</em>
