signifies standard temperature and pressure. This conditions are at 1
atmospheric pressure and 0 degrees Celsius. It has been said that at these
conditions, one mole of a gas molecule is equivalent to 22.4 liters of volume.
Therefore, the correct answer is option B. </span>
Answer:
the atomic number is 22
Explanation:
titanium is 22 on the periodic table. the amount of protons is the same as the atomic number
Molality is one way of expressing concentration of a solute in a solution. It is expressed as the mole of solute per kilogram of the solvent. To calculate for the molality of the given solution, we need to convert the mass of solute into moles and divide it to the mass of the solvent.
Molality = 29.5 g glucose (1 mol / 180.16 g ) / .950 kg water
Molality = 0.1724 mol / kg
The mass number for a carbon atom which contains 6 neutrons is 12.
