Answer : The formula mass of the compound in amu is, 217.62 amu

Explanation : Given,

29.2 % Copper by mass that means 29.2 grams of copper present in 100 grams of compound.

As we know that,

1 atom of copper has an atomic mass of 63.546 amu.

Now we have to determine the formula mass of the compound.

\text{Formula mass of compound}=\frac{\text{Atomic mass of copper}}{\text{Given mass of copper}}\times \text{Mass of compound}

\text{Formula mass of compound}=\frac{63.546amu}{29.2g}\times 100g=217.62amu

Therefore, the formula mass of the compound in amu is, 217.62 amu

In the first law of thermodynamics, △E = Q-w, what does △E stand for?
Damm [24]

<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.

A gas at 20.0°C and 52.1 mL is heated to 93.5°C. What is the new volume?
lawyer [7]
\frac{ V_{1} }{ T_{1} } = \frac{ V_{2} }{ T_{2} }
V_{1} = 0.0521 L
T_{1} = 293.15 K
T_{2} = 366.65 K

Solve for V_{2}

\frac{0.0521 L}{293.15 K} = \frac { V_{2} }{366.65 K}

V_{2} = 0.06516 L or 65.2 mL
