the link below said that a 30-degree Celsius temp at saturated vapor density will contain vapor of about 30.4 grams per m\^3
Does that mean the room with length = 220cm, width = 230cm, and height = 120cm will be 6,072,000 cm\^3 = 6.072 m\^3 >>>> 6\*30.4 = 182.4 g ??
but from what I have experimented with putting silica gel inside the room. I found that on the peak day, the weight of silica gel increased by approximately 12 grams/day (unknown relative humidity but surely higher than 95%) >>>> If you absorb 12 g of water from the saturated air (182.4g), the relative humidity should decrease by about 6% (I even further let my Farcent disposable dehumidifier increase its weight by 135g from absorbing water)
but what's wrong with my logic? the value displayed on the hygrometer doesn't even decrease a little bit
