What is the molarity of a solution that contains 5 moles of solute in 2 liters of solution?
* First! Figure out what pyridine's formula is: C5H5N So, we know that each molecule of pyridine has 5 C, 5 H, and 1 N. The cool thing about the formula is it doesn't matter what the unit is, as long as the ratio between the C, H, and N remains the same, BUT, being that we're doing chemistry let's use moles. :) 5 moles of C + 5 moles of H + 1 mole of N -->1 mole of C5H5N This can be a weird concept, because you might think "how do you put in 11 moles of stuff and get only one mole of product"... but, just like baking, you put in 5 cups of sugar, 5 cups of flour, and 1 cup of butter, but get one really big cookie (didn't say it would be a good cookie). Well, you put in a few moles of this, a few moles of that...and you get a single mole of C5H5N. * After you figure out the chemical formula, calculate molecular mass: 5 moles of carbon = 5 x 12.011 grams per mole = 60.055 grams 5 moles of hyrdrogen = 5 x 1.008 grams per mole= 5.04 grams 1 mole of nitrogen = 1 x 14.007 grams per mole= 14.007 grams ADD: 60.055 + 5.04 + 14.007 = 79.102 grams per 1 mole of C5H5N * Convert solute to moles! Now, we've figured out that 1 mole of C5H5N has a mass of 79.102 grams....but, we're only putting 5 grams in the solution. How many moles is 5 grams if 1 mole is 79.102 grams? Calculate: 5 grams/ 79.102 grams = .063 moles * Convert to moles per liter (not moles to part of a liter)! So...we are adding .063 moles to .5 liters of solvent, but, molarity is always expressed in moles per liter, so we have to convert this: (.063 moles C5H5N/.5 liter) x 1 liter = .126 moles C5H5N So, if .063 moles of C5H5N dissolved in .5 liters gives a solution of the same concentration as 1.26 moles of C5H5N dissolved in 1 liter (note - we now have it in moles per liter!). As molarity is moles per liter...and adding 5 grams of pyridine (which is .063 moles) to .5 liters of solvent produces a solution of the same concentration (molarity) as dissolving 1.26 moles of solvent in 1 liter, we have produced a 1.26 molar solution.
How many moles are there in 5gram of sulphur?
To find the number of moles in 5 grams of sulfur, you need to divide the mass of the sample by the molar mass of sulfur. The molar mass of sulfur is approximately 32.06 g/mol. Therefore, 5 grams of sulfur would be equal to 0.156 moles.
What is the mass of 5 moles of Potassium Sulphate?
The molar mass of Potassium Sulphate (K2SO4) is 174.26 g/mol. Therefore, the mass of 5 moles of Potassium Sulphate would be 5 moles x 174.26 g/mol = 871.3 grams.
How many moles in 200 grams of calcium?
There are 5 moles of calcium in 200 grams of calcium. This calculation is based on the molar mass of calcium, which is approximately 40 grams per mole.
How many moles of 5grams of oxalic acid?
To calculate the number of moles in 5 grams of oxalic acid (C2H2O4), first determine the molar mass of oxalic acid, which is 90.03 g/mol. Then, divide the mass (5 grams) by the molar mass to get the number of moles. In this case, 5 grams is equal to approximately 0.055 moles of oxalic acid.
If you need 5 moles of sulphuric acid how many grams of it will you weigh?
The mass of sulfuric acid is 490,395 grams.
How many moles of AgNO3 does 85 grams of AgNO3 represents?
To find the number of moles, you need to divide the given mass (85 grams) by the molar mass of AgNO3 (169.87 g/mol). 85 grams of AgNO3 represents 0.500 moles.
How many moles in 5 grams of NaCl?
For this you need the atomic mass of Na. Take the number of grams and divide it by the atomic mass. Multiply by one mole for units to cancel.11.5 grams Na / (23.0 grams) = .500 moles Na
How many moles are there in 5 grams of silicon dioxide?
To determine the number of moles in 5 grams of silicon dioxide (SiO2), you first need to calculate the molar mass of SiO2. The molar mass of SiO2 is 60.08 g/mol. Then, use the formula Moles = Mass / Molar mass to find that there are approximately 0.083 moles in 5 grams of SiO2.
How many grams of water are produced when 2.5 mil oxygen reacts with hydrogen?
When 2.5 moles of oxygen react with hydrogen, they react in a 1:2 ratio to produce water. Therefore, 2.5 moles of oxygen will produce 5 moles of water. To convert moles to grams, you'll need to know the molar mass of water, which is approximately 18 grams/mol. So, 2.5 moles of oxygen will produce 90 grams (5 moles x 18 grams/mole) of water.
How many gram-moles in 320 grams of SO2?
To determine the number of gram-moles in 320 grams of SO2, you first need to find the molar mass of SO2, which is 64.07 g/mol. Then you divide the given mass (320 g) by the molar mass to get the number of moles. Therefore, 320 grams of SO2 is equivalent to 5 moles.
How many grams of CO2 are produced from 5 moles O2?
5.0 grams CO2 (1mol CO2/44.01g) = 0.11 moles CO2
How many moles are there in 5 grams of potassium sulfate?
To find the number of moles in 5 grams of potassium sulfate (K2SO4), first calculate the molar mass of K2SO4 by adding the atomic masses of potassium (K), sulfur (S), and four oxygen (O) atoms. Then, divide the given mass (5 grams) by the molar mass of K2SO4 to get the number of moles.
How many grams of water can be prepared from 5moles of hydrogen at standard conditions?
At standard conditions, 1 mole of hydrogen reacts with 0.5 moles of oxygen to form 1 mole of water. Therefore, to form 5 moles of water, you will need 5 moles of hydrogen and 2.5 moles of oxygen. The molar mass of water is approximately 18 g/mol, so 5 moles of water would weigh 90 grams.
