In a chemical reaction you collect 1000 ml of hydrogen gas at stp how many moles of hydrogen gas did you collect 0.02 0.04 0.004 0.002

Option B = 0.04 mol

Explanation:

We were given the following:

Pressure = 1 atm (We know this because it was stated that the gas is at STP).

Volume = 1000ml = 1L (Converting to L by diving by 1000)

Temperature = 273.15k (We know this because it was stated that the gas is at STP).

We are to calculate the number of moles, n collected.

The Ideal Gas Equation relates all of these variables;

pV=nRT

where R = gas constant = 0.08206 L atm / K mol

making n subject of interest, we have;

n=pV / RT

Substituting the values of the variables and solving for n;

n = (1 * 1 ) / (0.08206 * 273.15)

n = 0.0446 mol

Approximately, n = 0.04 mol

answer; ///(d) the correct answer is double or triple

the answer is b. dilution
