Oxi Nặng Hơn Không Khí

     

Khí oxi nặng hơn không khí bao nhiêu lần? Từ đó, hãy cho biết để thu khí hidro vào bình bằng cách đẩy không khí, ta phải đặt đứng bình hay đặt ngược bình?Vì sao?

Đáp án:

Khí O2 có khối lượng là 32 g/mol. Con kk có khối lượng trung bình là 29. Vì vậy O2 nặng hơn kk 32/29 = 1,1 lần.

Để thu khí H2 vào bình bằng cách đẩy kk thì phải đặt ngược bình vì H2 nhẹ hơn kk sẽ bay lên trên.
