0.753 is the answer for this question
10^(-0.123)=0.753
Answer:It would be orange
Explanation:I hope this helps
From the Boyle's law, it is clear that volume is inversely proportional to pressure. Thus it is prudent to say that, P1V1=P2V2
From the question above,
P1=1atm
P2=3.8atm
V1=?
V2=7.6L
Hence, 1*V1=3.8atm*7.6L
V1=28.88L
Explanation:
You have a solution that contains 36 g HCl dissolved in 64 g water
Molar mass HCl = 36.45 g/mol
Mol HCl in 36 g = 36 g / 36.45 g/mol = 0.9876 mol
Molar mass H2O = 18 g/mol
Mol H2O in 64 g = 64 g / 18 g/mol = 3.5556 mol
Total mol = 0.9875 + 3.5556 = 4.5431 mol
Mol fraction HCl = 0.9876 mol / 4.5431 mol = 0.2174
Mol fraction H2O = 3.5556 / 4.5431 = 0.7826
The answer should have 2 significant digits:
Mol fraction HCl = 0.22
Mol fraction H2O = 0.78
Mol fraction has no units.
THAT IS HELPFUL FOR YOU
