Answer:
E. 1.5M
Explanation:
because there is total 175.32 g of NaCl dissolved in 2 liter of water, and 58.44 g = 1 mol
so total miles = 175.32/58.32 = 3 moles
now 3 moles are in 2 liter of water, hence one liter contains 3/2= 1.5
Therefore answer is E. 1.5M
Igneous rock that forms from magma that cools slowly within Earth’s crust is likely to have larger crystals and a coarse-grained texture.
Igneous rock that forms from lava that cools quickly on Earth’s surface is known as extrusive igneous rock. Another word for extrusive is volcanic.
Because the sample of igneous rock formed on Earth’s surface, it is extrusive. Because it’s composed of mostly light-colored minerals, it is likely felsic.
Because the sample of igneous rock formed within Earth’s crust, it is intrusive. Because it contains a very high concentration of dark-colored, high-density minerals, it is likely ultramafic.
The fact that gabbro is an igneous rock suggests that it was formed from the cooling and crystallization of magma. The fact that it is intrusive means that it formed within Earth’s crust. The fact that it’s mafic suggests that it contains a high concentration of dark-colored, high-density minerals.
Answer:
Density = mass/volume
= 44/22.4
= 1.96 gram/liter
The density of the Carbon Dioxide at S.T.P. (Standard Temperature and Volume) is 1.96 gram/liter.
Answer:
Thiols contain stronger acids than alcohols
Explanation:
Density = mass/volume = 800/200 =4 g/cm^3
