Answer:
Mass on the moon is 5.1 kg.
Explanation:
Given mass on earth = 5.1 kg
acceleration due to gravity on moon = 1.6 ms⁻².
The mass on the moon does not change because mass is the quantity of matter in the body regardless of its volume or of any forces acting on it.
Whereas the weight of the object changed.
Weight is the the force exerted on a body which is related to mass and expressed as W = mg.
W = weight of object m = mass of object and g = gravitational force
N stands for newton unit of weight.
Thus mass of the object on moon is same as on earth which is 5.1 kg.
Hydrolysis of Methyl Benzoate yields Benzoic Acid and Methanol. This reaction is also called as
Tranesterification (reverse of esterification). Acid in this reaction protonates the carbonyl oxygen, resulting in increasing electrophillic character of carbonyl carbon. Water acts as a nucleophile and methoxide leaves as a good leaving group.
Mechanism is shown below,
The amount of impurities i guess
I have a solution to a similar problem here but different given values.
Answer:
0.409 g
Explanation:
As stated, 1 mole of NaCl weighs 58.44 g.
A 0.02 M solution contains 0.02 moles per liter.
Hence, 1 litre would contain:
58.44 x 0.02 = 1.1688 g
However, there are only 350 ml, which is 0.35 liters.
Therefore, there would be 0.35 x 1.1688 g in total, 0.409 g
C. The mean of the 8th and 9th values
Explanation:
If there are 16 values in a data set in order from the smallest to the largest, the median is the mean of the 8th and 9th values in the sequence.
The median is the middle term in a sequence.
To find the median:
Arrange the numbers from the lowest to the highest;
if the numbers are even in order, the median is the mean of the middle numbers. We will have two middle numbers
For odd order, we will have just one number.
