Since water has a density of about 1g/mL, and we are assuming HCl and NaOH are mostly water, the total mass of the 2 solutions is 100 g.
Due to the conservation of mass, the mass of product must equal the total mass of reactant, therefore the final mass must also be 100 g.
There are 195 countries in the world today. This total comprises 193 countries that are member states of the United Nations and 2 countries that are non-member observer states: the Holy See and the State of Palestine.
There are 50 US states.
The United States currently administers 16 territories as insular areas:
American Samoa.
Guam.
Northern Mariana Islands.
Puerto Rico.
U.S. Virgin Islands.
This information is from three sources. United Nations, Wikipedia, and United States and their satellite states aka countries.
