2 answers:
Answer: The correct option is C.
Explanation: For a given chemical formula
3 different elements are present in this molecule that are Carbon, Hydrogen and Oxygen.
Number of Carbon atoms present = 3
Number of Hydrogen atoms = 6
Number of oxygen atoms = 2
Total number of atoms in the given molecule = 3 + 6 + 2 = 11
Hence, This molecule is made up of total 11 atoms of 3 different elements. Therefore, the correct option is C.

Answer:
30 Liters of 40% acid solution and 10 L of 60% acid solution is needed.
Explanation:
Let volume of the 40% acid solution be x.
Let volume of the 60% acid solution be y.
Volume of solution formed after mixing both solution = 40 L
x + y = 40 L..[1]
Volume of acid 40% solution = 40% of x= 0.4x
Volume of acid 60% solution = 60% of y= 0.6y
Volume of acid formed = 45% of 40 L =
..[2]
Solving [1] and [2]
x = 30 L , y = 10 L
30 Liters of 40% acid solution and 10 L of 60% acid solution is needed.
