First, calculate the molar mass of CH3OH
Atomic weight of carbon = 12.0107
Atomic weight of hydrogen = 1.00794
Atomic weight of oxygen = 15.999
Molar mass of CH3OH = 12.0107 + 4 * 1.00794 + 15.999 = 32.04146
Now determine how many moles you have by dividing the number of atoms by avogadro's number
moles = 9.83 x 10^24 / 6.0221409 x 10^23 = 16.3231
Now multiply the number of moles by the molar mass
16.3231 * 32.04146 = 523.0159557
Since we only have 3 significant figures, round the result to 3 significant figures.
523.0159557 grams = 523 grams</span>
Answer:
The strong acid reacts with the weak base in the buffer to form a weak acid, which produces few H+ ions in solution and therefore only a little change in pH.
Explanation:
When a strong acid is added to the buffer, the acid dissociates and furnish hydrogen ions which combine with the conjugate of the weak acid, forming weak acid. The weak acid dissociates to only some extent and can furnish only some protons and there is no significant change in the pH.
Hence, option B is correct.
Answer:
The somatosensory cortex is a region of the brain which is responsible for receiving and processing sensory information from across the body, such as touch, temperature, and pain.
Area 1 specifically is important in sensing the texture of an object. :)
Hope this helps!
Physical properties are those which can be observed without any change in composition of the substance. Hence, a is the answer.
