Answer:
C6H12O2 is the formula for Methyl pentanoate
By using the Luca's method.
Hi! Are you looking for molarity?
Answer:
Option (b) 0.67 M
Explanation:
The following Data were obtained from the question:
Mole of MgCl2 = 0.5 mole
Volume of solution = 750mL
Molarity of MgCl2 =?
Next, we shall convert the volume given from mL to L. This is illustrated below:
1000mL = 1L
Therefore 750mL = 750/1000 = 0.75L
Now we can obtain the molarity of MgCl2 as follow:
Molarity is defined as the mole of solute per unit litre of the solution i.e
Molarity = mole /Volume
Molarity = 0.5/0.75
Molarity of MgCl2 = 0.67 M
Answer & Explanation:
The given number above, 0.002353, may be rounded to only two significant figures by adding 1 to the 3 which is in the fourth place of the decimal position. This becomes, 0.0024. Addition of 1 was done because the number that follows 3 in the original number is 5.
