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 do you find the number of carbon moles in cholesterol c27h46o?
The number of atoms of an element in a molecule is the number subscript immediately following the element symbol in the formula for the molecule. The number of moles of anything in a compound depends on the amount of the compound, which is not stated.
How many hydrochloric molecules are needed to fulfill the conservation of mass?

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.
Is molecules a force?
Molecules are not a force, they have 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 grams are their in 3.4x10molecules of NH3?
The mass is 9,6.10e-22 g for 34 molecules.
How many grams are equivalent to 2.5x1021 molecules of water (H2O)?
The mass is 74,7 mg.
How many molecules are in 25.0 g NO2?
To find the number of molecules in 25.0 g of NO2, you can start by converting the mass to moles using the molar mass of NO2. Then, use Avogadro's number (6.022 x 10^23 molecules/mol) to convert moles to molecules.
If there are 6.022 x 10e23 molecules of platinum in every 195.08 grams of platinum how many molecules of platinum are there in a ring that's mass is 6.31 grams?
567.1 mass is the equal to 56789.0 intergram. XD
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.
