Liquid X is known to have a lower viscosity and lower surface tension than Liquid Y Use these facts to predict the result of eac

h experiment in the table below, if you can. experiment predicted outcome O mx will be greater than my O mx will be less than my O Ill y will be equal to my Wax-coated particles carefully put onto the surface of Liquid X or Liquid Y will stay on the surface, if the particles are small enough. The heaviest mass of particle x and my that will stay on each liquid's surface without sinking are measured. It's impossible to predict whether mx or my will be greater without more information. OFx will be greater than F)y 15.0 mL of Liquid X are poured into a beaker, and 15.0 mL of Liquid Y are poured FX will be less than Fr into an identical beaker. Stirrers in each beaker are connected to motors, and thewill be equal to P forces Fx and Fy needed to stir each liquid It's impossible to predict whether Fr or F will at a constant rate are measured. be greater without more information.

A chemist has 3.55x1022 molecules of nitrogen monoxide. How
Alina [70]

Answer:

<h2>0.059 moles</h2>

Explanation:

To find the number of moles in a substance given it's number of entities we use the formula

n =  \frac{N}{L} \\

where n is the number of moles

N is the number of entities

L is the Avogadro's constant which is

6.02 × 10²³ entities

From the question we have

n =  \frac{3.55 \times  {10}^{22} }{6.02 \times  {10}^{23} }  \\  = 0.05897...

We have the final answer as

<h3>0.059 moles</h3>

Hope this helps you
