Using this formula E = mc2, which is the formula formulated by Albert Einstein to get the energy where E is the units of energy, m is the mass and c is the speed of light. We can say that 1 g is equivalent to 0.001 kg. The speed of light is 38<span>. Substituting these values to the formula, we can get 90 terajoules.</span>

To make a 6.50M solution, how many moles of solute will be needed if 12.0 liters of solution are required

avanturin [10]

Answer:

78 moles of the solute

Explanation:

From the question;

Molarity of the solution is 6.50 M
Volume of the solution is 12.0 L

We want to determine the number of moles needed

We need to know that;

Molarity = Number of moles ÷ Volume

Therefore;

Number of moles = Molarity × Volume

Hence;

Number of moles = 6.50 M × 12.0 L

= 78 moles

Thus, the moles of the solute needed is 78 moles

If you have 730 moles of a gas at 304 Kelvin in a 4.50 Liter container what

vova2212 [387]

Answer:

4046atm

Explanation:

For this question you can use the ideal gas law,

<em /> $PV=nRT$ <em />

Where P is pressure, V is volume, n is moles of substance, R is the constant, and T is the temperature.

Because of the units given, R will equal .08026 $P=4046 atm$

<h3>Rearrange the equation to solve for pressure:</h3>

$P=\frac{nRT}{V}$

Then, plug in the values (I'll be excluding units for simplicity, but they all cancel out for pressure in atm):

$P=\frac{(730)(.08206)(304)}{4.5}$

This will give you:

$P=4046atm$
