Calculate the volume (in L) occupied by 3.40 g of NH3 at STP. (STP: 0 degree Celsius and 1 atmosphere of pressure).

Calculate the volume (in L) occupied by 3.40 g of NH3 at STP. (STP: 0 degree Celsius and 1 atmosphere of pressure).

Explanation:

To get the volume of ammonia gas at STP, calculate the number of moles of in the given amount.

Number of moles of gas is:

Since,

1 mol of any gas at STP occupies ------- 22.4 L of volume.

then,

0.2 mol of occupies how much volume?

Hence, the volume occupied by 3.40 g of ammonia at STP is --- 4.48 L.

answer; i do believe the correct answer is (river); /// good luck
