O-nitrophenol has a molecular weight of 301.3 grams per mole. Use this molecular weight to calculate how many grams it will take to prepare 10 ml of a 0.013 M solution of O-nitrophenol. Calculate the mass in grams of 4.46*10^{24} molecules of propylamine. The c...
Calculate the molarity of a 5% glucose solution. How many grams of glucose (C6H2O6 molecular mass=180 daltons) would be present in one liter of a 1M (molar) solution of glucose? To prepare a 248 mM sugar solution, how many sugars (molecular weight = 309 g/mol...
How many grams of glucose would you have to weigh to make 500 mL of a 0.5 M solution of glucose? 1. Using Avogadro's number, calculate the number of atoms in 0.005 kilograms of carbon. 2. If there are 'x' atoms in 5 grams of carbon, how many atoms are there in 5 grams of sil...
How could a simple osmometer be used to estimate the molecular weight of an unknown non-penetrating solute? Osmometer: The osmometer is a device that uses the principle of osmosis to calculate solute concentration in a solution. It can be utilized in the estimati...
Question: How many copper atoms are in a pure copper statue with a mass of 144 kg? Moles: The concept of the mole is very helpful to chemists as it allows them to convert masses of substance into the amount molecules of that substance and thereby conduct more balanced react...
Chirality of an atom is when the atom is attached to different functional groups. A chiral atom within the molecule provides it with optical activity and determines the number of stereoisomers. Stereoisomers differ in the spatial arrangements of the atoms....
