Number of moles:
1 mole ---------- 6.02x10²³ molecules
? moles --------- 9.45x10²⁴ molecules
1 x ( 9.45x10²⁴) / 6.02x10²³ =
9.45x10²⁴ / 6.02x10²³ => 15.69 moles of CH3OH
Therefore:
Molar mass CH3OH = 32.04 g/mol
1 mole ------------ 32.04 g
15.69 moles ----- mass methanol
Mass methanol = 15.69 x 32.04 / 1 => 502.7076 g

Answer:
The correct answer is B has a neutral pH
Explanation:
we all know that acid converts blue litmus to red on the other hand base converts red litmus paper to blue.
According to the question the blue litmus paper does not change its colour or it stays blue that means the pH of solution is neutral or7 which prevent the colour change of the litmus paper.
If the solution was acidic then the blue litmus paper changes into red .
Answer would be A)the atom
Answer:
D.) The higher vapor pressure of acetone results in more rapid evaporation and heat loss
Explanation:
Acetone being liquid with very low boiling point and hence can be easily be converted to gaseous state .
And ,
Therefore have higher vapour pressure and as liquid gets converted to gas , the process of evaporation takes place and leads to loss of heat .
Hence , from the given options , the most appropriate option according to given statement of the question is ( d ) .
