Kristen dissolves 49.24 grams of NaOH in enough water to make 195 mL of solution. What is the molarity of Kristen's solution? Round your answer to two digits after the decimal point.

M = 6.31 M

Explanation:

Data:

mass = 49.24 g of NaOH

solution volume = 195 mL = 0.195 L

MW NaOH = 39.99 g/mol

M = ?

The equation to calculate the molarity of a solution is as follows:

To calculate the moles of NaOH the following equation is used:

Where MW is the molecular weight of NaOH, now we must clear the moles from the previous equation.

We place the moles and the volume of the solution in the molarity equation

chemical energy is stored in the chemical bonds of atoms and molecules. it can only be seen when it is released in a chemical reaction. when chemical energy is released, the substance from which the energy came is often changed into an entirely different substance.

this chemical reaction releases energy in the form of light and heat. chemical energy is the potential energy stored in the arrangement of atoms within molecules. breaking chemical bonds requires energy, while forming new chemical bonds releases energy.

the atp molecule can store energy in the form of a high energy phosphate bond joining the terminal phosphate group to the rest of the molecule. in this form,energy can be stored at one location, then moved from one part of the cell to another, where it can be released to drive other biochemical reactions.

space exploration has led to the development and technological improvement of many everyday items. (if this answer is wrong i will find the right answer) : )
