<u>We are given:</u>

Mass of water: 119 grams

We know that one mole of a gas occupies 22.4L of volume

<u>Number of moles of water:</u>

Number of moles = given mass / Molar mass

Number of moles = 119 / 18             [molar mass of water = 18 grams/mol]

Number of moles = 6.61 moles

<u>Volume occupied:</u>

Volume = number of moles * 22.4 L

Volume = 6.61 * 22.4

Volume = 148L

Volume (in mL) = 1.48 * 10⁻¹ mL

As 1 L = 1000 g

so 119 grams = 0.119000 L

Hope it is helpful to u

How much water, in grams, can be made from 1.03 x <img src="https://tex.z-dn.net/?f=10%5E%7B24%7D" id="TexFormula1" title="10^{2
krok68 [10]

Answer:

30.8 g of water are produced

Explanation:

First of all we need the equation for the production of water:

2H₂ + O₂ → 2H₂O

2 moles of hydrogen react with 1 mol of oxygen in order to produce 2 moles of water.

As we assume, the oxygen in excess, we determine the moles of H₂.

1.03ₓ10²⁴ molecules . 1 mol/ 6.02ₓ10²³ molecules = 1.71 moles

Ratio is 2:2, so 1.71 moles will produce 1.71 moles of water

Let's convert the moles to mass: 1.71 mol . 18g / 1mol = 30.8 g of water are produced

In which step of a four-stroke engine cycle does the car release CO2, H2O, and CO?
In-s [12.5K]

Answer:

\boxed{\text{exhaust stroke}}

Explanation:

The four strokes are

  1. Intake: The mixture of air and fuel enters the cylinder.
  2. Compression: The mixture is compressed by a factor of about 11.
  3. Ignition: A spark ignites the fuel, which burns and produces CO₂, CO, and H₂O.
  4. Exhaust: The combustion products are expelled from the cylinder.

\text{The cylinder releases CO$_{2}$, CO, and H$_{2}$O during the }\boxed{\textbf{exhaust stroke}}
