Question

After 1.00 ml of water is completely vaporized to gas, how many milliliters of vapor are produced at standard temperature and pressure? (Density of water is 1.00 g/mL; molar volume of any gas at STP is 22.4 L/mol.)

Answer 1

d=m/V
1 g/mL = xg/1mL

x=1g

PV=nRT

find number of moles

n=(1g)/(18g/mol)= 0.05555 g/mol

T= 25 celsius = 298.15 K

P= 1 atm

r= 0.08206 Latm/Kmol

find V
