Answer:
Option C. 1.60x10^26 molecules
Explanation:
Avogadro's hypothesis proved that that 1 mole of any substance contains 6.02x10^23 molecules.
From the above, we understood that 1 mole of CCl4 contains 6.02x10^23 molecules.
If 1 mole of CCl4 contains 6.02x10^23 molecules,
then, 265 moles of CCl4 will contain = 265 x 6.02x10^23 = 1.60x10^26 molecules
From the calculation made above, 265 moles of CCl4 contains 1.60x10^26 molecules.
Answer:
2,780,000mg
Explanation:
Using the Metric Staircase photo provided, you can calculate how many mg there are in 2.78 kg by simply moving the decimal point six places to the right, since the "Kilo" step takes six places to move to the "Milli" step.
2.78 kg
---------------
2 7 8 0 0 0 0 .
we can see that the decimal point is moved to the right six places.

Answer:
<em>Solids</em><em> </em><em>do</em><em> </em><em>not</em><em> </em><em>undergo</em><em> </em><em>diffusion</em><em> </em><em>because</em><em> </em><em>it</em><em> </em><em>has</em><em> </em><em>a</em><em> </em><em>fixed</em><em> </em><em>structure</em><em> </em><em>(</em><em>vibrates</em><em> </em><em>in</em><em> </em><em>a</em><em> </em><em>fixed</em><em> </em><em>position</em><em>)</em><em> </em><em>and</em><em> </em><em>it</em><em> </em><em>also</em><em> </em><em>cannot</em><em> </em><em>be</em><em> </em><em>compressed</em><em>.</em><em> </em>
<em>Hoped</em><em> </em><em>this</em><em> </em><em>helped</em><em> </em><em>in</em><em> </em><em>any</em><em> </em><em>way</em><em> </em>

1.34 grams of MgNH4PO4*6H2O
Molar mass= 245.1 grams per mole
Moles of MgNH4PO4*6H2O=
(1.34 grams)(1 mole/245.1 grams fertilizer)=0.0054671563 moles fertilizer
MgNH4PO4*6H2O has 1 mole of Phosphorous, so:
0.0054671563 moles fertilizer(1 mole Phosphorous/1 mole fertilizer)
0.0054671563 moles Phosphorous (30.97 grams/ 1 mole)
=0.1693178295 grams Phosphorous
