A cubic decimeter is a liter, so we're talking 50L of oxygen gas at STP. 1mol of any gas at STP occupies 22.4L of space, so 50/22.4 = about 2.2mol of oxygen.

How many liters are in 5.4x1024 molecules of nitric oxide at STP?
The volume is 19,48 L.
How many oxygen molecules are present in 113.97 liters of oxygen gas at STP?
At STP, one mole of any gas occupies 22.4 liters. This is called molar volume. 113.97 liters ÷ (22.4 L/mol) = 5.09 moles Then convert moles to molecules (1 mole = 6.02 × 1023 molecules) 5.09 moles × (6.02 × 1023 molecules/mol) = 3.06 × 1024 molecules
How many oxygen molecules are in 9.1 L of oxygen gas at STP?
at stp 1 mole of a gas contains 22.4 litres. 9.1/22.4= .40625 moles o2. 1 mole of a gas contains 6.022E23 molecules so .40625 moles x 6.022E23 = 2.4464325E23 molecules, but you have to multiply by two due to it being diatomic, so answer x 2 = 4.892875E23 molecules
How many moles of methane are presentin 5.6L of the gas at stp?
0.25 moles
How many moles are present in 8.4 liters of nitrous oxide at STP?
8,4 liters of nitrous oxide at STP contain 2,65 moles.
How many moles are contained in 16.8 L of Xe gas at STP?
16,8 L of Xe gas at STP is equivalent to 0,754 moles.

How many molecules are in 30 liters of methane (CH4) at STP
How many molecules of ethane are present in 64.28 liters of ethane gas (C2H6) at STP?
at STP 1 mole occupies 22.4 litres. 64.28 / 22.4 is 2.8696428 moles. Multiply this by avagadro's constant (6.022*10^23) gives 1.7281x10^24 molecules
How many moles are in 5.60 L Cl2 at STP?
17.7
How many moles of H2 gas are present in 6.0 L flask at stp?
The answer is 0,2675 moles.
How many moles of nitrogen does it take to fill a 60.0 liter space of stp?
The answer is 2,68 moles.
How many moles of argon are found in a 5L sample of argon at STP?
Approx 0.223 moles.
How many moles are present in 10.0 L of nitrogen gas at STP?
Assuming ideal behaviour, 1 mole of any gas occupies 22.4L at STP. So, moles of 10L = 10/22.4 moles = 0.4464 moles
