HNO3 molar mass = 1 + 14 +3*16 = 63 g/mol
# of moles = mass / molar mass - 25.0 g / 63 g = 0.3968 moles
# of atoms = # of moles * Avogadro number = 0.3968 mol * 6.022 *10^23 atoms/mol = 2.39 * 10^23 atoms

Explanation:
B, Hcl + NaoH = NaCl + H2O
Answer:
temperature of the water
Explanation:
Density is defied as mass divided by the volume. To investigate how the density of water change with temperature, Bob have the change the temperature and read the volume and mass of the investigated sample.
Even if there is a different salt content between booted water or tap water and have an influence on the density (compared with pure water), this difference is not so big so the change in density with temperature can be determined. Considering that the experiment do not require extreme accuracy, any type of water may be used (bottled water of tap water).
Yes what the other person said can I plz get an thanks
