How do you calculate the grams of an element in a specific amount of a compound?

To calculate the grams of an element in a compound, you need to find the molar mass of the element and the compound. Then, use the formula: (mass of element/molar mass of compound) x molar mass of element. This will give you the grams of the element in 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 do you calculate the percentage of water in a hydrate?

To calculate the percentage of water in a hydrate, you first determine the molar mass of the water and the compound. Then, you divide the molar mass of the water by the molar mass of the hydrate and multiply by 100 to get the percentage.


What is the mass percent of chlorine in chloroform CHCl3?

To calculate the mass percent of chlorine in chloroform (CHCl3), you would first find the molar mass of the compound, which is 119.38 g/mol. Then, determine the molar mass of chlorine in the compound, which is 35.453 g/mol. Calculate the mass percent of chlorine by dividing the molar mass of chlorine by the molar mass of the compound and multiplying by 100. In this case, the mass percent of chlorine in chloroform is about 29.7%.


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
