If the air has 10 g of water vapor yet it could hold 40 g, what is the relative humidity? A. 25% B. 20% C. 40% D. 4%

Sagot :

I think it's a.25 because if it holds 40g but has 10g then the 10g is about 25 percent because: 4g = 10 percent 2g = 5 percent So to get to 10g you have to do 4+4+2, which is 10+10+5 percent which= 25percent. Hope I helped!
