What is the molarity of a solution containing 400 grams of CuSO4 in 4.00 L of solution?

Molarity is defined as the number of moles of solute dissolved in 1 L of solution.

The mass of CuSO₄ - 400 g

molar mass of CuSO₄ - 159.5 g/mol

Therefore number of CuSO₄ moles - 400 g/ 159.5 g/mol = 2.51 mol

the volume of the solution is - 4.00 L

We need to find the number of moles in 1.00 L

If 4.00 L contains - 2.51 mol

Number of moles in 1.00 L - 2.51 mol / 4.00 L = 0.628 mol

Molarity - 0.628 M

the practice of taking someone else's work or ideas and passing them off as one's own.

explanation:

you need to take a look at the periodic system in order to sort these elements into pairs that would most likely exhibit similar chemical properties. first, you need to find elements that are found in the same group (groups are vertical in the periodic system), and then to see whether they have the same valence number. if they meet these criteria, they will have similar properties.

the first pair: ne (neon) and kr (krypton), are noble gases found in group 8

the second pair: li (lithium) and k (potassium), found in group 1

the third pair: s (sulfur) and te (tellurium), found in group 6
