Put this in scientific notation. 10 m to centimeters and 37.5 g/mL to kg/L
noname [10]

1m = 100cm

so 10m = 100*10 = 1000cm or in scientific notation 1.00x10^3 cm

1g = 1/1000kg

1mL = 1/1000L

so 1g/mL = (1/1000)/(1/1000)kg/L

=1kg/L

37.5g/mL = 37.5kg/L or 3.75*10^1 kg/L

What is the volume at stp of 720.0 ml of a gas collected at 20.0 °c and 3.00 atm pressure?
MArishka [77]
Combined gas law is 
       PV/T = K (constant)

P = Pressure
V = Volume
T = Temperature in Kelvin

For two situations, the combined gas law can be applied as,
     P₁V₁ / T₁ = P₂V₂ / T₂

P₁ = 3.00 atm                                     P₂ = standard pressure = 1 atm
V₁ = 720.0 mL                                    T₂ = standard temperature = 273 K
T₁ = (273 + 20) K = 293 K
  
By substituting,
 3.00 atm x 720.0 mL / 293 K = 1 atm x V₂ / 273 K
                                          V₂ = 2012.6 mL

hence the volume of gas at stp is 2012.6 mL
