Question

how many moles are contained at 5.33l of o2 at a standard temperature and pressure

Answer 1

Answer:

222,25 mol

Explanation:

Standard mole mass of O2 is equal to 31,9988 g/mol

Volume mass of O2 is equal to 1,308 g/L

x = 5,33*1,308*31,9988 = 222,25 mol

Answer 2

n=0.238

Explanation:

• We are asked to find the number of moles of O2 at standard temperature and pressure.

• The standard temperature and pressure are 0°C and 1 atm .

• The corresponding value of R is 0.082057 L atm mol-1 K-1.

• It is given that we are supposed to calculate the number moles for O2 for 5.33l.

• By substituting we get,

$1*5.33=n*0.082057*273\\\\n=\frac{5.33}{0.0821*273} \\\\n=0.238$
