The volume of the diluted (i.e the new) solution given the data is 147 mL

<h3>Data obtained from the question </h3>
  • Molarity of stock solution (M₁) = 1.85 M
  • Volume of stock solution (V₁) = 84 mL
  • Molarity of diluted solution (M₂) = 1 M
  • Volume of diluted solution (V₂) = ?

<h3>How to determine the volume of diluted solution </h3>

M₁V₁ = M₂V₂

1.75 × 84 = 1 × V₂

V₂ = 147 mL

Thus, the volume of the new solution is 147 mL

How do we know that galaxy clusters contain a lot of mass in the form of hot gas that fills spaces between individual galaxies?.
Olin [163]

while the gas  is detected with X-ray telescopes, that's how we get to know  that galaxy clusters contain a lot of mass in the form of hot gas that fills spaces between individual galaxies

The galaxy may be a gravitationally bound substance, ordinarily comprising dark matter, gas, dust, and stars. Galaxies populate the Universe, primarily residing in groups and clusters. Most galaxies have an add up to mass between ~ 107 M⊙ and 1012 M⊙. The galaxies within the Universe are always changing – through secular advancement, mergers, and interactions. An X-ray telescope may be a telescope that's outlined to observe farther objects within the X-ray spectrum. The fundamental components of the telescope are the optics ( collimating), which collects the radiation entering the telescope, and the detector, on which the radiation is collected and measured. An assortment of different plans and advances have been utilized for these elements.
