What is the gram molecular mass of a compound if 5 moles of the compound has a mass of 100 grams?
To find the gram molecular mass of the compound, you can use the formula: mass = moles × gram molecular mass. Given that 5 moles of the compound have a mass of 100 grams, you can rearrange the formula to find the gram molecular mass: gram molecular mass = mass / moles. Thus, gram molecular mass = 100 grams / 5 moles = 20 grams per mole.
Formula for moles?
number of moles = mass of the material/molar mass
How many moles are in 10003 grams of Hydrogen?
To find the number of moles in 10,003 grams of hydrogen, we use the molar mass of hydrogen, which is approximately 1 gram per mole. Thus, the number of moles is calculated by dividing the mass by the molar mass: [ \text{Moles of H} = \frac{10003 , \text{grams}}{1 , \text{gram/mole}} = 10003 , \text{moles}. ] Therefore, there are 10,003 moles of hydrogen in 10,003 grams.
How many moles of Na SO4 are in 25.0 of this compound?
To find the number of moles of Na2SO4 in 25.0 g of the compound, you need to convert the mass to moles. First, determine the molar mass of Na2SO4, then divide the given mass by the molar mass to obtain the number of moles.
What is the mass of 2.47 moles of fluorine atoms?
The gram atomic mass of fluorine is 18.9984. Therefore, the mass of 2.47 moles is 2.47 times the gram atomic mass, or about 46.9 grams, to the justified number of significant digits.
Which statement shows how to correctly convert from the mass of a compound in grams to the amount of that compound in moles?
To convert from the mass of a compound in grams to the amount of that compound in moles, you need to divide the mass of the compound in grams by its molar mass (which is found on the periodic table). This will give you the number of moles of the compound. The formula to use is: moles = mass (g) / molar mass.
What do you do to convert grams to moles?
The molar mass of a compound is expressed in grams.
What is the mass in grams of 8.56 moles?
This depends on the compound.
Formula for moles?
number of moles = mass of the material/molar mass
How many moles in potassium bicarbonate?
You did not describe the amount of potassium bicarbonate amount in grams in your question. But if you are about 1 gram of potassium bicarbonate it will be 0.0099 moles in one gram of potassium bicarbonate. 0.0199 moles in 2 grams of potassium bicarbonate.
What is the mass of kbr in 2.50 moles of the compound?
The mass number of potassium is about 39. The mass number of bromine is about 80. Total is 119. 119* 2.5 = 297.5. So 297.5 grams of potassium bromide has got 2.5 gram moles.
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 MOLES of sodium nitrate are present in 2.85 grams of this compound?
To find the number of moles, first calculate the molar mass of sodium nitrate (NaNO3), which is 85 grams/mol. Then, divide the given mass (2.85 grams) by the molar mass to obtain the number of moles present, which is approximately 0.0335 moles.
How many moles of CCl4 are present in 22.5 g of the compound?
For this conversion, you need the atomic masses of the elements involved, found on any periodic table. Then you add them up with their abundance in the compound to find the total molar (molecular) mass. The molar mass is the mass in grams of one mole of the compound. Carbon = 12.0 grams Chlorine = 35.5 grams × 4 atoms = 142.0 grams ------------------------------------------------------------- Carbon tetrachloride = 154.0 grams/mole Then you do a gram --> mole conversion, taking the amount given and dividing it by the molar mass. Grams ÷ Molar mass = Moles 22.5 grams ÷ 154.0 grams = 0.146 moles CCl4
How many moles are in gram of NaOH?
moles = mass/Mr moles = 100/(23+16+1) moles of NaOH = 2.5mol
How many moles of Na SO4 are in 25.0 of this compound?
To find the number of moles of Na2SO4 in 25.0 g of the compound, you need to convert the mass to moles. First, determine the molar mass of Na2SO4, then divide the given mass by the molar mass to obtain the number of moles.
What is the mass of 2.47 moles of fluorine atoms?
The gram atomic mass of fluorine is 18.9984. Therefore, the mass of 2.47 moles is 2.47 times the gram atomic mass, or about 46.9 grams, to the justified number of significant digits.
