Convert 4.2 moles of C2H6 gas to volume at STP

1 answer:

When gases are in STP, it doesn't matter what the compound or chemical the gas is: there are 22.4 liters in a mole. No matter what. (Note that this is for STP and STP only! If you get a question like this and it's not in STP, disregard this rule!)

Knowing this, in order to calculate volume all we have to do is multiply it by 22.4:
4.2 * 22.4 = 94.08

There are 94 liters in C2H6 gas at STP
-T.B.

An experimental spacecraft consumes a special fuel at a rate of 372 L/min. The density of the fuel is 0.730 g/mL and the standar

Karolina [17]

Explanation:

First, we will calculate fuel consumption is as follows.

$372 L/min \times 1000 ml/L \times 0.730 g/ml \times \frac{1}{60} min/s$

= 4526 g/s

Now, we will calculate the power as follows.

Power = Fuel consumption rate × -enthalpy of combustion

= $4526 g/s \times -26.5 kJ/g$

= $1.19 \times 10^{5}$ kW

Thus, we can conclude that maximum power (in units of kilowatts) that can be produced by this spacecraft is $1.19 \times 10^{5}$ kW.

Find the number of moles of butane (c4h10) in 21g sample of butane gas

iogann1982 [59]

Answer:

0.362 moles

Explanation:

Mass of butane = 21g

Molar mass of carbon = 12g / mol

Molar mass of hydrogen = 1g/mol

Molar mass of butane ? = [(12*4) * (1*10)]

Molar mass of butane = 58g / mole

Number of moles = mass of molecules / molar mass of molecule

Number of moles = 21 / 58

Number of moles of butane = 0.362 moles

The number of moles in 21g of butane is 0.362 moles
