The molecular weight of it is 386.654g/mol. Convert mass to grams (i.e. 0.0039g). divide mass by molec weight to get 1.0083573x10^-5 moles. Multiply this by avagadros number to get the amount of molecules. this gives you 6.072x10^18 molecules.

How many hydrogen atoms present in 2grams cholesterol?

To find the number of hydrogen atoms in 2 grams of cholesterol, you need to first calculate the molar mass of cholesterol (about 386 g/mol) and then divide the given mass by the molar mass to find the number of moles. Next, use the molecular formula of cholesterol (C27H46O) to determine the number of hydrogen atoms in one mole of cholesterol. Finally, multiply this number by the number of moles to find the total number of hydrogen atoms present in 2 grams of cholesterol.


If the yellow molecules have a molecular mass of 25 amu what is the molecular mass of the blue molecules?

Without additional information, it is impossible to determine the molecular mass of the blue molecules based solely on the molecular mass of the yellow molecules. Each type of molecule has its own unique molecular mass, and it cannot be inferred from other molecules.


How many grams are equivalent to 2.5x1021 molecules of water (H2O)?

The mass is 74,7 mg.


How many grams are in 4.1 X 1022 molecules of N2I6?

To calculate the number of grams in 4.1 x 10^22 molecules of N2I6, you first need to find the molar mass of N2I6. Then, use this molar mass to convert the number of molecules to grams using Avogadro's number and the formula: grams = (number of molecules) / (Avogadro's number) * molar mass.


What is the mass of 3.97x1021 molecules dinitrogen tetraoxide?

To calculate the mass of 3.97x10^21 molecules of dinitrogen tetraoxide, you first need to find the molar mass of dinitrogen tetraoxide (N2O4), which is about 92.02 g/mol. Then you can use Avogadro's number (6.022x10^23 molecules/mol) to convert molecules to moles and then multiply by the molar mass to find the mass.

How many molecules are contained in a 4.40-g sample of dimethylmercury?

To determine the number of molecules in a sample, you need to know the molar mass of the substance. The molar mass of dimethylmercury (CH3)2Hg is approximately 230.65 g/mol. Utilizing the formula: moles = mass/molar mass, and then using Avogadro's number (6.022 x 10^23 molecules/mol), you can calculate the number of molecules in the sample.

How many molecules are contained in a 7.85-g sample of dimethylmercury?

To determine the number of molecules in a sample, we need to know the molar mass of dimethylmercury (C2H6Hg). The molar mass of dimethylmercury is approximately 230.62 g/mol. Using this molar mass, we can calculate that there are approximately 2.23 x 10^22 molecules in a 7.85-g sample of dimethylmercury.
