<span>The equation that produces carbon disulfide from the reaction of coke and sufur dioxide is expressed in the balanced equation: c+ 2sO2 = CS2 + 2O2. For every mole of coke reacted, there is one mole of carbon disulfide produced. Hence the answer here is 8 moles of CS2 </span>

Charra [1.4K]

Answer:

The molar mass of the metal is 54.9 g/mol.

Explanation:

When we work with gases collected over water, the total pressure (atmospheric pressure) is equal to the sum of the vapor pressure of water and the pressure of the gas.

Patm = Pwater + PH₂

PH₂ = Patm - Pwater = 1.0079 bar - 0.03167 bar = 0.9762 bar

The pressure of H₂ is:

0.9762bar.\frac{1atm}{1.013bar} =0.9637atm

The absolute temperature is:

K = °C + 273 = 25°C + 273 = 298 K

We can calculate the moles of H₂ using the ideal gas equation.

P.V=n.R.T\\n=\frac{P.V}{R.T} =\frac{0.9637atm \times 0.249L }{(0.08206atm.L/mol.K)\times298K} =9.81 \times 10^{-3} mol

Let's consider the following balanced equation.

M(s) + H₂SO₄(aq) ⟶ MSO₄(aq) + H₂(g)

The molar ratio of M:H₂ is 1:1. So, 9.81  × 10⁻³ moles of M reacted. The molar mass of the metal is:

\frac{0.539g}{9.81 \times 10^{-3} mol} =54.9g/mol

How many grams are in 2.5 moles of Carbon
Jet001 [13]
According to the periodic table, carbon's molar mass is 12.011 grams per mole (that's the small number under the element).  So, just multiply like this to get the answer:

(2.5\ mol\ C)(\frac{grams\ C}{12.011\ mol\ C})=0.20814\ g\ C

So, there are approximately 0.208 grams in 2.5 moles of carbon.
