Molar volume is when 1 mol of any gas occupies 22.4 L at STP.
Methyl ether has a mass of 8.12 g,
Volume occupied - 3.96 L
If 22.4 L occupied by 1 mol of gas
Then 3.96 L occupied by 1/22.4 x 3.96 = 0.176 mol of gas
The mass of 0.176 mol = 8.12 g
Molar mass is mass of 1 mol
Therefore mass of 1 mol = 8.12/0.176 = 46.1
Molecular weight is 46.1 g/mol

<h3> The supplements that are minerals are</h3>
  1. calcium
  2. sodium
  3. iron
  4. zinc

<u><em> Explanation</em></u>

  • calcium   and sodium  are major  minerals   which are required  by the body for

      calcium-  needed  for muscle,hearing bone and  for the support of synthesis and function of cells

     sodium-   is needed to control blood  pressure  and  also for proper  muscle and nerve  function

  • Zinc  and iron are  required   in trace and both are needed for good health

How much heat is needed warm 65.34 g of water from 18.43 to 21.75
BaLLatris [955]

Given that  

Mass of water = 65.34 g

Amount of heat = mass of water * specific heat (temperature change

)

= 65.34 g * 4.184 J / g-C ( 21.75-18.43 )C

= 907.63  J  

= 0.908 KJ

And  

1 cal = 4.186798 J

907.63 J * 1 cal / 4.186798 J =216.78  cal

Or0.218 kcal

How do modern scientists describe the makeup of matter?
zavuch27 [327]
Any substance made out of iotas, that has mass and possesses space. Matter ought not be mistaken for mass, as the two are not the same in current material science. Matter is itself a physical substance of which frameworks might be formed, while mass isn't a substance but instead a quantitative property of issue and different substances or frameworks. While there are diverse perspectives on what ought to be viewed as issue, the mass of a substance or framework is the same regardless of any such meaning of issue. Another distinction is that issue has an "inverse" called antimatter, however mass has no inverse—there is no such thing as "hostile to mass" or negative mass. Antimatter has the same (i.e. positive) mass property as its typical issue partner.
