A sample of dry gas weighing 2.1025 g is found to occupy 2.850 L at 22.0oC and 740.0 mm Hg. How many moles of gas are present?
soldi70 [24.7K]

0.11 moles of the gas are present in the sample of dry gas.

Explanation:

Data given:

mass of the gas  = 2.1025 grams

volume of the gas = 2.850 litres

temperature =  22 degrees (273.15+22) = 295.15 K

Pressure = 740 mm Hg or 0.973 atm

moles of the gas =?

R = 0.08206 atmL/Mole K

From the ideal gas law the number of moles can be calculated in the sample of dry gas. Number of moles will be determined by the pressure exerted, volume and temperature of the gas.

The formula:

PV = nRT

n = \frac{PV}{RT}

putting the values in the above equation:

n = \frac{2.850 x 0.973}{0.08206 X 295.15}

  = 0.11 moles

0.11 moles of the dry gas is present in the sample given.

How many moles of glucose, C H O , can be "burned" biologically when 18.2 mol of oxygen is available? C H O (s) + 6O (g) --->
Feliz [49]
Answer:
              547.7 g of C₆H₁₂O₆

Solution:
               The balance chemical equation is as follow,

                           C₆H₁₂O₆  +  6 O₂    →    6 CO₂  +  6 H₂O

According to equation,

                         6 moles of O₂ burns  =  180.56 g of C₆H₁₂O₆
So,
                18.2 moles of O₂ will burn  =  X g of C₆H₁₂O₆

Solving for X,
                      X  =  (18.2 mol × 180.56 g) ÷ 6 mol

                      X  =  547.7 g of C₆H₁₂O₆

Answer:

λ = 2.8 m

Explanation:

Given data:

Frequency of radio wave = 106.7 ×10⁶ Hz

Wavelength of radio wave = ?

Solution:

Formula:

Speed of wave = frequency  × wavelength

speed of wave = 3×10⁸ m/s

by putting values,

3×10⁸ m/s = 106.7 ×10⁶ Hz × λ

Hz = s⁻¹

λ = 3×10⁸ m/s / 106.7 ×10⁶ Hz

λ =  3×10⁸ m/s / 106.7 ×10⁶ s⁻¹

λ =  0.028×10² m

λ = 2.8 m
