Weight/volume  percentage  =  mass of  the  solute/volume  of  solution  x    100

mass of  the   solute=  12grams
volume  of  solution  =  400ml
therefore  %  (w/v)  =  12 /  400  x100  =  3%

Calculate the mass of butane needed to produce 97.4 g of carbon dioxide. Express your answer to three significant figures and in
Vsevolod [243]

Answer:

32.1 g

Explanation:

Step 1: Write the balanced combustion reaction

C₄H₁₀ + 6.5 O₂ ⇒ 4 CO₂ + 5 H₂O

Step 2: Calculate the moles corresponding to 97.4 g of CO₂

The molar mass of CO₂ is 44.01 g/mol.

97.4 g × 1 mol/44.01 g = 2.21 mol

Step 3: Calculate the moles of butane that produced 2.21 moles of carbon dioxide

The molar ratio of C₄H₁₀ to CO₂ is 1:4. The moles of C₄H₁₀ required are 1/4 × 2.21 mol = 0.553 mol

Step 4: Calculate the mass corresponding to 0.553 moles of C₄H₁₀

The molar mass of C₄H₁₀ is 58.12 g/mol.

0.553 mol × 58.12 g/mol = 32.1 g

What is the speed of a wave with a wavelength of 3 m and a frequency of .1 Hz?
ratelena [41]

Answer:

wave velocity= frequency × wave length

=1×3

=3m/s

Explanation:

The distance covered by the wave in one second is equal to its wavelength, therefore,

wave velocity=wavelength/time period

OR wave velocity= frequency× wavelength

You can assume velocity as speed here.
