Neutron is subatomic particel with with mass approximately one atomic mass unit, and neutron mass slightly larger than proton.
neutron have natural charge and i suppose that the mass may be called as: a. mass number of 1.
hope this help
<u>Given:</u>
Volume of HCl (VHCl) = 25,0 ml = 0.025 L
Volume of NaOH (VNaOH) = 22.15 ml = 0.02215 L
Molarity of NaOH (MNaOH) = 0.155 M
<u>To determine:</u>
Molarity of HCl
<u>Explanation:</u>
Titration reaction-
HCl + NaOH → NaCl + H2O
Based on the reaction stoichiometry:
1 mole NaOH requires 1 mole HCl
# moles of NaOH = VNaOH * MNaOH = 0.02215*0.155 = 0.003433 moles
# moles of HCl = # moles of NaOH = 0.003433 moles
Molarity of NaOH = 0.003433/0.025 = 0.137 M
Answer:
Molecular mass of NH3 = ( 14 + 3 ) = 17 g
