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 grams of water are released when a 10.0-g sample of CaSO42H2O?
To calculate the grams of water released from a sample of CaSO4·2H2O, we need to determine the molar mass of the compound, then calculate the molar mass of the water in that compound. The molar mass of CaSO4 is about 136.14 g/mol, and the molar mass of 2H2O is about 36.03 g/mol. Therefore, the mass of water released would be 36.03 g/mol * 10.0 g / 136.14 g/mol = 2.65 g.
