Yes how about you luv? how’s ur day going
Explanation:
Molarity is defined as number of moles per liter of solution.
Mathematically, molarity =
It is given that molarity is 0.0800 M and volume is 50.00 mL or 0.05 L.
molarity =
0.0800 M =
no. of moles = 1.6 mol
Therefore, molar mass of cupric sulfate pentahydrate is 249.68 g/mol. So, calculate the mass as follows.
No. of moles =
mass in grams =
=
= 399.488 g
Thus, we can conclude that 399.488 g of cupric sulfate pentahydrate are needed to prepare 50.00 mL of 0.0800M CuSO4× 5H2O.
Answer:
Bacteria reproduce by binary fission. In this process the bacterium, which is a single cell, divides into two identical daughter cells. Binary fission begins when the DNA of the bacterium divides into two (replicates). ... Each daughter cell is a clone of the parent cell.
Explanation:
First, determine the number of moles of gold.
Number of moles =
Given mass of gold =
Molar mass of gold = 196.97 g/mol
Put the values,
Number of moles of gold =
= or
Now, molarity =
Put the values, volume of ocean =
Molarity =
=
Thus, average molar concentration =
