the sum of the atomic weights for all the atoms in the formula
To calculate the volume of a compound when given its molecular weight and weight, you need to first convert the weight to moles using the molecular weight. Then, you can use the density of the compound to find the volume by dividing the weight in moles by the density. The formula is volume = weight (in moles) / density.
No, you do not need to know the atomic weight to calculate molarity. Molarity is calculated by dividing the moles of solute by the volume of solution in liters. Knowing the atomic weight can help determine the number of moles in a given mass of solute, but it is not required to calculate molarity.
To calculate the Fe content in FeO, you need to consider that Fe accounts for about 71.85% of the FeO compound's molecular weight. For Fe2O3, each Fe atom accounts for about 69.94% of the compound's molecular weight. After determining the molecular weight of FeO and Fe2O3, you can find the Fe content by multiplying the molecular weight of Fe by the appropriate percentage.
The equivalent weight of a salt is the molecular weight of the salt divided by the number of ions produced when the salt dissolves in water. It is used to calculate the amount of salt needed in a reaction based on the amount of ions present.
To find water by mass in a compound, you can calculate the difference in mass before and after heating the compound to drive off the water. The lost mass represents the mass of water present in the compound. You can then calculate the percentage of water in the compound by dividing the mass of water by the total mass of the compound and multiplying by 100.
Gram equivalent weight is calculated by dividing the molar mass of the compound by the number of equivalents of the species involved in the reaction. It is a measure of the mass of a substance that provides one equivalent of the species of interest in a chemical reaction.
To determine the equivalent weight from the molecular weight, you need to divide the molecular weight by the valence (or charge) of the compound. For example, for a compound with a molecular weight of 100 g/mol and a valence of 2, the equivalent weight would be 50 g/equiv.
To calculate the equivalent weight of an oxide, you first determine its molecular weight. Then you look at how many oxygen atoms are present in the formula of the oxide and divide the molecular weight by that number of oxygen atoms. This result is the equivalent weight of the oxide.
To calculate the volume of a compound when given its molecular weight and weight, you need to first convert the weight to moles using the molecular weight. Then, you can use the density of the compound to find the volume by dividing the weight in moles by the density. The formula is volume = weight (in moles) / density.
Between 1.154 and 1.158 grams per centimeter cubed.

The equivalent weight of calcium chloride (CaCl2) is 55.5 g/mol. This is the amount of the compound that can donate or accept one mole of electrons in a reaction.
The milligram equivalent weight of sodium sulfate is 142.04 mg, calculated by dividing the molecular weight of the compound (142.04 g/mol) by 1000 to convert it to milligrams.
The equivalent weight of glucose is 180 g/mol. This is calculated by dividing the molecular weight of glucose (180 g/mol) by the number of equivalents of reactive atoms in the compound, which in this case is 1.
No, you do not need to know the atomic weight to calculate molarity. Molarity is calculated by dividing the moles of solute by the volume of solution in liters. Knowing the atomic weight can help determine the number of moles in a given mass of solute, but it is not required to calculate molarity.
The equivalent weight of ammonium thiocyanate is calculated by dividing the molecular weight by the total positive or negative charge of the compound. For ammonium thiocyanate (NH4SCN), the molecular weight is approximately 76.12 g/mol and the total positive charge is +1 (from the ammonium ion), so the equivalent weight is 76.12 g/mol.
To calculate the mass in grams of each sample, you can use a balance or scale to measure the weight of the sample. The weight measured in grams is equivalent to the mass of the sample.
