Explanation:

<u>Atomic mass</u>: The sum of no. of protons and no. of neutrons

<u>Protons</u>: a subatomic particle with a positive charge

<u>Neutron</u>: a subatomic particle with no charge (neutral)

<u>Isotopes: </u>the same elements with different atomic mass [Eg. uranium-235, uranium-238. Uranium being one element, can have different mass numbers. Hence Uranium-238 is an isotope of Uranium-235]

<u>Therefore</u>:

<h3>Proton + neutrons= Atomic mass</h3><h3>Δatomic mass= formation of isotopes. </h3>

<em>*Δ= Change in</em>

Molarity =  Moles/Liter

Use the molecular atomic mass of NaCl to convert from grams to moles.
Molecular mass of NaCl is the sum of its atomic masses. Look at the periodic table to find these. Na is 23 g/mol and Cl is 35.5 g/mol ,
so NaCl = 23 + 35.5 = 58.5 g/mol

multiply to cancel out grams
76 g NaCl * (1mol / 58.5 g NaCl) = 1.3 mol NaCl

over 1 Liter is just 1.3 M NaCl
Hope this helps!

A chemist has some 40% acid solution, some 60% acid solution, and a wholebunch of free time. How many liters of each should be u
TiliK225 [7]

Answer:

30 Liters of 40% acid solution and 10 L of 60% acid solution is needed.

Explanation:

Let volume of the 40% acid solution be x.

Let volume of the 60% acid solution be y.

Volume of solution formed after mixing both solution = 40 L

x + y = 40 L..[1]

Volume of acid 40% solution = 40% of x= 0.4x

Volume of acid 60% solution = 60% of y= 0.6y

Volume of acid formed = 45% of 40 L = \frac{45}{100}\times 40=18L

0.4x+0.6y=18 L..[2]

Solving [1] and [2]

x = 30 L  ,   y = 10 L

30 Liters of 40% acid solution and 10 L of 60% acid solution is needed.
