A molecule may be nonpolar either when there is an equal sharing of electrons between the two atoms of a diatomic molecule or because of the symmetrical <span>arrangement of polar bonds in a more complex molecule.</span>
1 mol of formic acid is correct. There are two oxygen atoms in formic acid, compared to just one for the other molecules.
Answer:
A. Magnesium
Explanation: Its because Magnesium is Heavier than Bromine and there is 24.3050 atom in Magnesium but there is only two in Bromine
I Hope This Helps:)
Answer: Scientific notation-
Explanation: I got this by moving the decimal, so that there is one non-zero digit to the left of that decimal point. Tip- The number of decimal places you move will be the exponent on the 10.
Moved right- Negative
Moved left- Positive
<u>Answer:</u> The molarity of solution is 1.08 M
<u>Explanation:</u>
We are given:
(m/m) of phenol = 1.40 %
This means that 1.40 g of phenol is present in 100 g of solution.
To calculate volume of solution, we use the equation:
Density of solution = 0.9956 g/mL
Mass of solution = 100 g
Putting values in above equation, we get:
To calculate the molarity of solution, we use the equation:
We are given:
Mass of solute (phenol) = 1.40 g
Molar mass of phenol = 94.11 g/mol
Volume of solution = 100.442 mL
Putting values in above equation, we get:
Hence, the molarity of solution is 0.15 M
