Answer:

V=37.05\ L

Explanation:

Given that:

Mass of NO, m = 45.0 g

Molar mass of NO, M = 30.01 g/mol

Temperature = 20.0 °C

The conversion of T( °C) to T(K) is shown below:

T(K) = T( °C) + 273.15  

So,  

T₁ = (20.0 + 273.15) K = 293.15 K

V = ?

Pressure = 740 mm Hg

Considering,  

n=\frac{m}{M}

Using ideal gas equation as:

PV=\frac{m}{M}RT

where,  

P is the pressure

V is the volume

m is the mass of the gas

M is the molar mass of the gas

T is the temperature  

R is Gas constant having value = 62.36367 L. mmHg/K. mol

Applying the values in the above equation as:-

740\times V=\frac{45.0}{30.01}\times 62.36367\times 293.15

740V=\frac{822685.94372}{30.01}

V=37.05\ L

The density of water is 1.00g/cm3. Express this density in lb/m3​
Ira Lisetskai [31]

Answer:  2205 lb/m^3

Explanation:  

  • 1g = 0.002205lb
  • 1cm^3 = 1x10^-6m^3

Convert:  (1g/cm^3)*(0.002205lb/g)*(1cm^3/1x10^-6m^3) = 2205 lb/m^3
