The melting point of ice is 0°C: thus is a fact based on repetitive experiments


Repeated observations have consistently

shown that oppositely charged objects

attract each other: this is law


When the elements carbon and nitrogen

are mixed at 1500°C, they will react

with each other.

this is a hypothesis

Atoms are made of protons, neutrons,

and electrons. Although we can’t directly

see these particles, this structure

explains many experimental observations

What is the molarity of a solution of 17.0 g of nh4br in enough h2o to make 158 ml of solution? answer in units of m?
vivado [14]
Unit of M is also mole/L, where mole is the moles of solute and L is the volume of the solution.  The latter is given: 158 mL or 0.158 L.  So we need to find out the moles of NH4Br.

Moles of NH4Br = Mass of NH4Br/molar mass of NH4Br = 17.0g/(14+1*4+79.9)g/mol = 0.1736 mole.

So, the molarity of the solution = 0.1736mole/0.158L = 1.10 mole/L = 1.10 M
