1.75 (moles O2) × 6 (moles H2O) ÷ 9 (moles O2) = 1.17 (moles H2O)
You have to convert moles of O2 into moles of H2O so it's the number of moles you start with (1.75 O2) × the number of moles from the element you want (6 H20), then ÷ by the number of moles that the element that you already have (9 O2).
The mass of butane gas at the given volume and Standard temperature and pressure is 0.0022g.
<h3>What is Ideal Gas Law?</h3>
The Ideal gas law or general gas equation emphasizes on the state or behavior of a hypothetical ideal gas. It states that "the pressure multiplied by volume is equal to moles multiply by the universal gas constant multiply by temperature.
It is expressed as;
PV = nRT
Where P is pressure, V is volume, n is the amount of substance, T is temperature and R is the ideal gas constant ( 0.08206 Latm/molK )
Given the data in the question;
- Volume of the gas V = 3L
- At STP; P = 1.0atm, T = 273.15K
- Amount of gas n = ?
PV = nRT
n = PV / RT
n = ( 1.0atm × 3.00L ) / ( 0.08206 Latm/molK × 273.15K )
n = 3.00Latm / 22.41 Latm/mol
n = 0.13mol
Now, since Molar mass of brutane gas is 58.12 g/mol.
Mass = n × Molar mass
Mass = 0.13mol × 58.12 g/mol
Mass = 0.0022g
Therefore, the mass of butane gas at the given volume and Standard temperature and pressure is 0.0022g.

Sonar uses [sound] waves to tell how [far away] things are in the water.
Safety information can be found on the MSDS, the material safety data sheet. Where your schools keep the MSDS is not something I can tell you, but you shoudl have them on file in your chemical storage room. Many companies do not send these out anymore so you may have to get them online.
