Answer:
The molar mass of the acid is 1067.42 g/mol
Explanation:
A monotropic acid can donate one proton only in a acd base reaction thus
Monotropic acid + NaOH → NaSalt + H₂O
From the above reaction, one mole of NaOH reacts with one mole of monotropc acid
however there are 0.1578 M NaOH from 15.24 mL hence we have
Number of moles of NaOH = 0.1578 M/L × (15.24/1000) L = 0.002404872 M of NaOH
The number of moles of the monotropic acid = number of moles of NaOH = 0.0024 M. However Number of moles = mass/(molar mass)
Therefore molar mass = mass/number of moles = 2.567(2.4×10⁻³) = 1067.42 g/mol
<span>A decrease in the temperature of a contained liquid causes a decrease in vapor pressure. The liquid absorbs the air as it expands when it is cooled and nearing freezing point, which leads to the decrease in vapor pressure. </span>
Answer:
d) 2, 4-Dimethylpentane
Explanation:
2, 4-Dimethylpentane is the c_7 compound that gives 3 signals in the broadband proton decoupled ¹³C spectrum.
This compound is classified as an alkane and it's chemical formula is [(CH3C)2CH]2CH2. It is a hydrocarbon that has no odor. When it is combined with other gas compounds it gives high octane fuel.
I suppose because of the fact that the relative humidity is taking away your heat and making you feel cool, I think that you would feel cooler than someone who was dry.
