Answer:

The correct answer is nanoscale.

Explanation:

A branch of nanotechnology that utilizes standard size apparatuses to produce basic compositions and tools with dimensions on the range of few nanometers or even less, that is, 1 nm is equivalent to a billionth of a meter, that is, it operates at an atomic level. It has an application in sanitation, water purification, medicine, agriculture, and others.

A chemist adds of a sodium thiosulfate solution to a reaction flask. Calculate the mass in grams of sodium thiosulfate the chemi

schepotkina [342]

This is a incomplete question.The complete question is:

A chemist adds 180.0 ml of a 1.77 mol/L of sodium thiosulfate solution to a reaction flask. Calculate the mass in grams of sodium thiosulfate the chemist has added to the flask. Be sure your answer has the correct number of significant digits.

Answer: 50.4 g

Explanation:

To calculate the number of moles for given molarity, we use the equation:

$\text{Moles of solute}={\text{Molarity of the solution}}\times{\text{Volume of solution (in L)}}$ .....(1)

Molarity of sodium thiosulfate solution = 1.77 M

Volume of sodium thiosulfate solution = 180.0 mL = 0.1800 L

Putting values in equation 1, we get:

$\text{Moles of sodium thiosulfate}={1.77}\times{0.1800}=0.319moles$

Mass of sodium thiosulfate = $moles\times {\text {Molar mass}}=0.319moles\times 158.11g/mol=50.4g$

Thus 50.4 g of sodium thiosulfate the chemist has added to the flask.

laila [671]

Answer is: A. 1 molecule with 10 atoms.
Every ball represent one atom in one molecule.
The ball and stick model is a molecular model of a chemical substance that shows the three-dimensional position of the atoms and the bonds between them. The atoms have spherical shape and they are connected with sticks (one, two or three, depends on bonds).
