The student who performed this experiment in the question above wrote the following discussion: "The gas sample is known to cont

ain compounds of only hydrogen and carbon. The measured molecular weight of the flammable gas is closest propane (44.1 g/mole), but lies between propane and butane (58.1 g/mole). I therefore conclude that there is a possibility that the sample is not a pure compound but rather is equal parts propane and butane." This seems qualitatively reasonable except her hypothesis that the gas is a 1:1 mixture is not supported by the data. What gas mixture is suggested by the molecular weight measured in the experiment? Give the percent propane in the mixture in the box provided. Do not enter the percent symbol. Enter your answer with the correct number of significant digits.

What volume, in mL, of concentrated 16 M nitric acid would you need to use in order to prepare 500.0 mL of a 0.250 M HNO3(aq) so
shtirl [24]

Given :

Initial concentration of nitric acid, C_1 = 16\ M.

Final concentration of nitric acid, C_2 =  0.250 \ M.

Volume of HNO_3, V _2= 500\ mL = 0.5\ L .

To Find :

Volume needed( V_1 ).

Solution :

We know,

C_1V_1 =C_2V_2\\\\16 \times V_1 = 0.250 \times  0.5 \\\\V_1 = \dfrac{0.250 \times  0.5}{16}\\\\V_1 = 0.0078125\ L = 7.8125 \ mL

Hence, this is the required solution.

Aneli [31]
The correct answer is <span>A. The transfer of heat and energy

Sound waves, electron movement, and conservation of matter are studied by different parts of physics. Thermo is an ancient root word/prefix that is used to refer to heat. An example of that is a Thermos, which is supposed to save heat of a liquid.</span>
