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.

A sample of the compound prepared in this experiment weighing 0.1021 g is dissolved in HNO?

To calculate the concentration of the sample, you need to know the volume of HNO3 used to dissolve it. Once you have that information, you can use the formula: concentration (mol/L) = mass of sample (g) / molar mass of compound (g/mol) / volume of HNO3 (L).


How many molecules are contained in a 5.00 g sample of dimethylmercury?

To determine the number of molecules in a sample, you need to know the molar mass of the compound. For dimethylmercury, the molar mass is approximately 230.6 g/mol. You can then use the formula n = m/M, where n is the number of moles, m is the mass of the sample, and M is the molar mass, to calculate the number of molecules in the sample.


How many molecules are in sample 57.45 CF2Cl2?

To calculate the number of molecules in a sample, you need to know the mass of the sample and the molar mass of the compound. Then you can use Avogadro's number (6.022 x 10^23) to convert from grams to molecules.


How do you work out the number of moles of unknown compound if you are only given the molar mass?

To find the number of moles from molar mass, divide the mass of the compound by its molar mass. The formula is: Moles = Mass (g) / Molar Mass (g/mol). This will give you the number of moles of the unknown 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.

How many formula units would there be in a 54.3 gram sample of sodium nitrate?

To determine the number of formula units in a sample of a compound, you first need to calculate the molar mass of the compound. Sodium nitrate has a molar mass of 85 grams/mol. Next, you convert the given mass of the sample (54.3 grams) to moles by dividing by the molar mass. This gives you approximately 0.639 moles of sodium nitrate. Since one mole of a compound contains Avogadro's number of formula units (6.022 x 10^23), the 54.3 gram sample of sodium nitrate would contain approximately 3.85 x 10^23 formula units.
