Hey there!
Great question=)

Answer: Contrast-Same chemical composition. Granite is intrusive, when rhyolite is extrusive!
Compare-Different cooling rates.

Answer:

Explanation:

Hello,

In this case, we say that rhyolite is very closely related to granite, nonetheless rhyolite has a larger a mount of finer crystals than granite, which are as tiny as they are not possible to be seen by a simple look with out eyes. Moreover, rhyolite is an extrusive igneous rock that was formed by cooling down more rapidly than granite which provide it a glassy glance. Additionally, rhyolite is made up of quartz, feldspar, mica, and hornblende.

On the other hand, the granite is a shiny-like igneous rock with visible grans by a simple look (unlike rhyolite). It is formed when a sluggish crystallization of magma is carried out underground. It is majorly made up of quartz and feldspar with traces of mica, amphiboles, and other minerals.

Best regards.

A solution is made by dissolving 58.125 g of sample of an unknown, nonelectrolyte compound in water. The mass of the solution is
e-lub [12.9K]

Answer:

molecular weight (Mb) = 0.42 g/mol

Explanation:

mass sample (solute) (wb) = 58.125 g

mass sln = 750.0 g = mass solute + mass solvent

∴ solute (b) unknown nonelectrolyte compound

∴ solvent (a): water

⇒ mb = mol solute/Kg solvent (nb/wa)

boiling point:

  • ΔT = K*mb = 100.220°C ≅ 373.22 K

∴ K water = 1.86 K.Kg/mol

⇒ Mb = ? (molecular weight) (wb/nb)

⇒ mb = ΔT / K

⇒ mb = (373.22 K) / (1.86 K.Kg/mol)

⇒ mb = 200.656 mol/Kg

∴ mass solvent = 750.0 g - 58.125 g = 691.875 g = 0.692 Kg

moles solute:

⇒ nb = (200.656 mol/Kg)*(0.692 Kg) = 138.83 mol solute

molecular weight:

⇒ Mb = (58.125 g)/(138.83 mol) = 0.42 g/mol
