Molarity= moles/liter, so you would need 3mol KBr/1 liter
(0.3M)(1L)= 0.3mol KBr
First, find out how many grams are in one mole of CO2(the two oxygen atoms means you need to multiply oxygen’s amu by 2,then add whatever carbon’s amu is to that). Then divide 26 grams by that number and that will be your moles. There are only two significant figures, so round your answer correctly.
Answer:
1. C 2. B 3. A
Explanation:
1. Gay- Lussac law, states that as along as the volume is kept constant, the pressure of a fixed mass of gas is directly proportional to the temperature.
The properties it compares is; (c.) Pressure and temperature
2. Boyle's Law states that; as long as the temperature is kept constant, the volume of a fixed mass of gas is inversely proportional to the pressure.
It therefore compares; (b.) Pressure and volume
3. Avogadro's Law states that equal volumes of different gases contain the same number of molecules provided the temperature and pressure are the same.
It therefore compares; (a.) Volume and moles

<span>Titanium is the first element in the fourth column of the periodic table. It is classified as a transition metal. Titanium atoms have 22 electrons and 22 protons. Titanium is fairly inactive and is very resistant to corrosion from other elements and substances like acids and oxygen. It has a relatively low electrical and thermal conductivity. Titanium is used to alloy with different metals such as iron, aluminum, and manganese where it helps to produce strong and lightweight alloys for use in spacecraft, naval ships, missiles, and as armor plating.</span>
