Hey there!:

Molar mass H3PO4 = <span>97.9952 g/mol

Atomic Masses :

H = </span><span>1.00794 a.m.u

</span>P = <span>30.973762 a.m.u

</span>O =  15.9994 a.m.u<span>

How much heat is added if .0948g of water is increased in temperature by .728 degrees C?
Verdich [7]

Answer:

0.289J of heat are added

Explanation:

We can relate the change in heat of a substance with its increasing in temperature using the equation:

q = m*ΔT*S

<em>Where Q is change in heat</em>

<em>m is mass of substance (In this case, 0.0948g of water)</em>

<em>ΔT = 0.728°C</em>

<em>S is specific heat (For water, 4.184J/g°C)</em>

Replacing:

q = 0.0948g*0.728°C*4.184J/g°C

q = 0.289J of heat are added
