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.
