<u>Answer: </u>The correct answer is Option B.

<u>Explanation:</u>

First law of thermodynamics states that the energy can neither be destroyed not be formed but it can only be transformed from one form to another.

Here, the internal energy of the system is being transformed to the heat energy and the work done by the system. The equation used to represent first law of thermodynamic is:

\Delta E=Q-w

where,

\Delta E represents the internal energy of the system.

Q = heat released or absorbed by the system.

w = work done by or on the system.

Hence, the correct answer is Option B.

Calculate the mass of 0.00456 moles of (NH4)2SO4
Anna [14]
To find the mass you need to find the weight of a mol of the molecules by adding up the atomic mass.

N =  14.007 g/mol
H = 1.008 g/mol
S = 32.065 g/mol
O = 16 g/mol

2(14.007) + 8(1.008) + 32.065 + 4(16) = 132.143 g/mol

Now you know how much an entire mol weight you multiply it by how much you actually have 

0.00456 * 132.143 = 0.603 g
