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.
How many moles in the compound magnesium sulfate and water?
To determine the number of moles in a compound like magnesium sulfate and water, you need to know the mass of each individual component in the compound. Then you can use the molar mass of each substance to convert the masses to moles using the formula: moles = mass / molar mass. Keep in mind that in a compound like magnesium sulfate and water, you need to consider the molar ratios of each component in the compound.
How can one determine the empirical formula from moles in a chemical compound?
To determine the empirical formula from moles in a chemical compound, you first need to find the moles of each element present in the compound. Then, divide the moles of each element by the smallest number of moles to get the simplest whole number ratio. This ratio represents the empirical formula of the compound.
How many moles of MgCl2 are there in 313 g of the compound?
Approx 3.29 moles.
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 the element oxygen are in 4.00 moles of the compound K2Cr2O7?
The formula means, among other things, that there are 7 atoms of oxygen in each mole of the compound. Therefore, in 4.00 moles of the compound, there are 28.00 moles of oxygen atoms. Elemental oxygen usually is diatomic, so that there would be the equivalent of 14 moles of diatomic elemental oxygen.
How do you find the number of moles of hydrogen there are in 3.5 moles of NH42 CO3?
To find the number of moles of hydrogen in 3.5 moles of (NH4)2CO3, first identify the stoichiometry of the compound. In (NH4)2CO3, there are two moles of hydrogen per mole of compound. Therefore, in 3.5 moles of (NH4)2CO3, there would be 2 * 3.5 = 7 moles of hydrogen.
If 3.50 of the unknown compound contained 0.117 of C and 0.233 of H how many moles of oxygen were in the sample?
To find the moles of oxygen in the compound, first calculate the moles of carbon and hydrogen using their respective molar masses. Then, subtract these totals from the total moles present in the compound to find the moles of oxygen.
How to determine the empirical formula of a compound?
To determine the empirical formula of a compound, you need to find the ratio of the elements present in the compound. This can be done by analyzing the mass percentages of each element in the compound and converting them into moles. Then, divide the moles of each element by the smallest number of moles to find the simplest whole number ratio. This ratio represents the empirical formula of the compound.
What is the number of moles represented by 38.1g?
This depends on the compound !
What is the mass in grams of 8.56 moles?
This depends on the compound.
