What is the percentage composition of molar mass in the given compound?
The percentage composition of molar mass in a compound is the percentage of each element's mass contribution to the total molar mass of the compound.
What is the molar mass of the nonelectrolyte compound if a 4.305 g sample of it is dissolved in 105 g of water?
To find the molar mass of the nonelectrolyte compound, we need to use the formula: Molar mass (mass of compound / moles of compound) First, we need to find the moles of the compound by using the formula: moles mass / molar mass Given that the mass of the compound is 4.305 g and it is dissolved in 105 g of water, we can calculate the moles of the compound. Next, we can find the molar mass of the compound by rearranging the formula: Molar mass mass / moles By plugging in the values, we can calculate the molar mass of the nonelectrolyte compound.
How many moles of MgCl2 are there in 317 g of the compound?
To find the number of moles of MgCl2 in 317 g of the compound, first calculate the molar mass of MgCl2 (95.21 g/mol). Then, divide the given mass by the molar mass to get the number of moles: 317 g / 95.21 g/mol = 3.33 moles of MgCl2.
What are the steps for calculating molar mass of compound?
molar mass is the atomic mass of the element. it's on the Periodic Table. you just have to add them up. unless you want to calculate the number of moles in a compound, in that case: moles = mass/molar mass
What is the molar mass of a compound if 25.0 g of the compound dissolved in 750 mL gives a molarity of 0.290 M?
1st convert mL to L: 750mL x (1L/1000mL)= 0.75L 2nd find the number of moles: 0.75L x (0.290mol/ 1L)= 0.2175mol 3rd now find the MM(Molar Mass): 25g x (1g/ 0.2175 mol) = 114.9 g/mol or 115g
The combustion data for an unknown compound containing carbon hydrogen and oxygen was analyzed and the empirical formula for the unknown was found to be C3H5O The molar mass of the unknown was found?
To find the molecular formula from the empirical formula (C3H5O) and molar mass, you need to calculate the molar mass of the empirical formula. Then, divide the molar mass of the unknown compound by the molar mass of the empirical formula to get a ratio. Finally, multiply the subscripts in the empirical formula (C3H5O) by this ratio to determine the molecular formula of the unknown compound.
What is the percentage composition of molar mass in the given compound?
The percentage composition of molar mass in a compound is the percentage of each element's mass contribution to the total molar mass of the compound.
A student has one mole of an unknown compound in a test tube The mass of the compound is 58.5 g The compound could be -?
The compound could be sodium chloride (NaCl) since its molar mass is 58.5 g/mol, which matches the given mass.
Does the molar mass of a compound change depending on the weight of the compound?
Molar mass depend on the ,mass,type and number of atoms in molecules of compound.
How many moles of sodium sulfate are in 0.1000g of the compound?
To find the number of moles of sodium sulfate in 0.1000g of the compound, you first need to determine the molar mass of Na2SO4. Then, divide the given mass by the molar mass to get the moles.
The combustion data for an unknown compound containing carbon hydrogen and oxygen was analyzed and the empirical formula for the unknown was found to be C3H4O The molar mass of the unknown was fou?
C6h12o3
