Answer:
the mass of one mole of an element, or Avogadro's number (6.02 x 1023) of atoms, is equal to its atomic mass in grams. In other words, 1 amu = 1 gram/mole. So if the mass of one hydrogen atom is 1 amu, the mass of one mole of hydrogen is 1 gram.

Answer:
At dynamic equilibrium, the reactions continue but the amounts of reactants and products do not change.
Explanation:
At dynamic equilibrium, the reactions continue but according to the law of conservation of mass, the amounts of reactants and products don't change.
Answer: The new volume is 95.45 mL.
Explanation:
Given: 
= 45.0 mL, 
= 0.98 atm
= 2.1 atm, 
= ?
According to Boyle's law, at constant temperature the pressure of a gas is inversely proportional to its volume.
Therefore, formula used to calculate the new volume is as follows.
Substitute the values into above formula as follows.
Thus, we can conclude that the new volume is 95.45 mL.
