Answer:

C₆H₈O₆

Explanation:

The molecular formula of given compound is C₆H₈O₆. Because there are six carbon, six oxygen and eight hydrogen atom present in this compound.

The molecular weight of following compound is,

C₆H₈O₆

C = 12 amu

H = 1 amu

O = 16 amu

C₆H₈O₆ = 12×6 + 1×8 + 16×6

C₆H₈O₆ = 72 +8 + 96

C₆H₈O₆ = 176 g/mol

41 g of MgCl^2 is how many moles of magnesium chloride?
kari74 [83]

Answer:

0.43 mol.

Explanation:

  • Knowing that the no. of moles can be calculated using the relation:

<em>no. of moles (n) = mass/molar mass</em>

mass of MgCl₂ = 41.0 g & molar mass of MgCl₂ = 95.211 g/mol.

<em>∴ n = mass/molar mass</em> = (41.0 g)/(95.211 g/mol) = <em>0.43 mol.</em>

A mixture of three gases has a pressure at 298 K of 1380 mm Hg. The mixture is analysed and is found to contain 1.27 mol CO2, 3.
enot [183]

Answer:

The partial pressure of Ar is 356.04 mm Hg (= 0.4685 atm)

Explanation:

<u>Step 1:</u> Data given

A mixture of three gases has a total pressure of 1380 mm Hg (=1.81579 atm) at 298 K

Moles of CO2 = 1.27 moles

Moles of CO = 3.04 moles

Moles of Ar = 1.50 moles

<u>Step 2:</u> Calculate total number of moles

Total number of moles = n(CO2)+ n(CO)+ n(Ar) = 1.27 mol+ 3.04 mol+ 1.50 mol = 5.81 moles

<u>Step 3:</u> Calculate mol fraction Ar

Mol fraction Ar = 1.50 mol/5.81 mol = 0.258

<u>Step 4</u>: Calculate partial pressure

1380 mm Hg * 0.258 moles Ar = 356.04 mm Hg = 0.4685 atm

The partial pressure of Ar is 356.04 mm Hg (= 0.4685 atm)
