A scientist collects 0.24 mole of hydrogen gas in a balloon. The temperature of the hydrogen is 35 degrees Celsius, and the pres
slava [35]

Answer:

             5.77 L

Solution:

Data Given:

                Moles  =  n  =  0.24 mol

                Temperature  =  T  =  35 °C + 273  =  308 K

                 Pressure  =  P  =  1.05 atm

                 Volume  =  V  =  ?

Formula Used:

Let's assume that the hydrogen gas in balloon is acting as an Ideal gas, the according to Ideal Gas Equation,

                 P V  =  n R T

where;  R  =  Universal Gas Constant  =  0.082057 atm.L.mol⁻¹.K⁻¹

Solving Equation for V,

                 V  =  n R T / P

Putting Values,

                 V  =  (0.24 mol × 0.082057 atm.L.mol⁻¹.K⁻¹ × 308 K) ÷ 1.05 atm

                 V  = 5.77 L

Can someone please help with chemistry? Lead has a density of 10.5 g/cm^3. What is the diameter of a lead ball that has a mass o
adelina 88 [10]
Density = Mass / Volume

10.5 = 500 / x

10.5x = 500

x = 50 cm^3 (1 sig fig) volume of the sphere

Volume of a sphere = 4/3 pi r^2

pi = 3.14 r = radius

50 = 4/3 pi r^3

50•3/4 = pi r^3

37.5 = pi r^3

37.5/pi = r^3

11.9 = r^3

cube root(11.9) = r

2.3 = r

Diameter = 2•radius

Diameter = 2 • 2.3

Diameter = 5 cm (1 sig fig) diameter
