The number of moles of the gas is 0.0396 moles.

<h3>What is the ideal gas equation?</h3>

The ideal gas equation is used to determine the relationship between the variables; temperature, pressure, volume and the number of moles of a gas. We know that the gas laws are used to understudy the parameters that has to do with gases.


Thus;

Volume = 1000.0 cm 3 or 1 L

Gas constant = 0.082 atmLK-1Mol-1

Temperature = 32 o C + 273 K = 305 K

Pressure =  752 mm Hg  or 0.99 atm

Thus;

PV = nRT

n = PV/RT

n =  0.99 atm *  1 L/0.082 atmLK-1Mol-1 * 305 K

n = 0.0396 moles

Given that a 12.00 g milk chocolate bar contains 8.000 g of sugar, calculate the percentage of sugar present in 12.00 g of milk
neonofarm [45]
So in order for us to know the percentage of sugar present in a 12.00 g of milk chocolate, what we are going to do is that, we just have to divide 8 by 12 and multiply in by 100 and we get 66.67. Therefore, the percentage of sugar present in 12.00 g of milk chocolate bar is 66.67%. Hope this answers your question. Have a great day!

4.50 g of NaCl reacts with 10.00 g of AgNO3 to produce 7.93 g of AgCl. If the theoretical amount of AgCl that can be formed is 8
olga nikolaevna [1]

Answer: 94.07%

Explanation:

Percentage yield can be calculated by the formula

%yield = Experimental yield/Theoretical yield x100

Experimental yield = 7.93g

Theoretical yield = 8.43

%yield = Experimental yield/Theoretical yield x100

%yield = 7.93/8.43 x 100 = 94.07%
