2.50 x 2/1 = 5 mol of Citric Acid
5 x (3+72+5+112) = 960g of Citric Acid
Answer: 960g of Citric Acid
Answer: The number of molecules of gas the flask contains is 
Explanation:
According to ideal gas equation:
P = pressure of gas = 1 atm (STP)
V = Volume of gas = 2.50 L
n = number of moles = ?
R = gas constant =
T =temperature = 273K (STP)
According to Avogadro's law:
1 mole of gas at STP contains =
molecules
Thus 0.112moles of gas at STP contains =
molecules
The number of molecules of gas the flask contains is 
Answer:
In the case of the Hardwood floor vacuum, you have to use a vacuum cleaner to clean hardwood floors. If you use a hard-bristled broom, it can damage the exterior of Hardwood floors. On the other hand, the vacuum creates less airborne dust and doesn't damage the surface of hardwood floors.When done correctly, the vacuuming process can remove more soil from a floor than a dust mop or broom. ... “The vacuum sucks up and removes all the dust, even the fine dust. It removes all the soil.” Vacuums typically do a better job than mops at reaching dirt in cracks and corners

Answer:
<h3>The answer is 2 moles</h3>
Explanation:
To find the number of moles in a substance given it's number of entities we use the formula

where n is the number of moles
N is the number of entities
L is the Avogadro's constant which is
6.02 × 10²³ entities
From the question
N = 1.204 × 10²⁴ atoms of gold
We have

We have the final answer as
<h3>2 moles</h3>
Hope this helps you
