The partial pressure of oxygen is 4.84 atm, and the partial pressure of carbon dioxide is 4.37 atm.
Moles of O₂ = 52.5 g O₂ × (1 mol O₂/32.00 g O₂) = 1.641 mol O₂
Moles of CO₂ = 65.1 g CO₂ × (1 mol CO₂/44.01 g CO₂) = 1.479 mol CO₂
Total moles = (1.641 + 1.479) mol = 3.120 mol
Let<em> O₂ be Gas 1</em> and <em>CO₂ be Gas 2</em>.
χ₁= 1.641/3.120 = 0.5259
χ₂= 1.479/3.120 = 0.4741
<em>p</em>₁ = χ₁<em>p</em>_tot = 0.5259 × 9.21 atm = 4.84 atm
<em>p</em>₂ = χ₂<em>p</em>_tot = 0.4741 × 9.21 atm = 4.37 atm
Answer:
9.0 moles Ca(NO₃)₂
Explanation:
from definition of Molarity = moles of solute / volume of solution in liters
=> moles = Molarity x Volume(L) = 6.00 molar x 1.5 liters = 9.0 moles Ca(NO₃)₂
Answer:
Helps in accepting and defending the conclusion.
Explanation:
The main advantages of having proof before you make any conclusion is that it gives a reason for accepting the answer given by you because you have the proof to prove your answer so no one questions on your answer. The proof give you strength to defend your conclusion and make your conclusion right in front of the world. Without proof no one can accept your answer because every answer of a scientific question wants a proof for its validation.
Answer:
Density, mass of a unit volume of a material substance. The formula for density is d = M/V, where d is density, M is mass, and V is volume. Density is commonly expressed in units of grams per cubic centimetre. ... For example, the density of air is 1.2 kilograms per cubic metre.
Answer:
The correct option is A
Explanation:
Water from a river is used for many activities in a community. These activities could include (but not limited to) tourism, drinking for animals, local transport, irrigation for nearby farming, recreation (as in swimming), habitat for some living organisms among others. Rivers are not limited by what limits the influence of oceans such as taste (it's saltiness, which cannot be used in farming also) and wave current.
