Calculate the amount of cuso4•5h2o required to make 25 ml of a 0.45 m solution of cuso4.

Mass = 1.76 g

Explanation:

Given data:

Volume of solution = 25 mL

Molarity = 0.45 M

Amount of CuSO₄.5H₂O = ?

Solution:

Molarity = number of moles / volume in litter

Number of moles = Molarity × Volume in L

Number of moles = 0.45 M  × 0.025 L

Number of moles = 0.011 mol

Mass of f CuSO₄.5H₂O:

Mass = Number of moles ×  molar mass

Mass = 0.011 mol × 159.6 g/mol

Mass = 1.76 g

coral.

explanation:

coral. many marine organisms that produce calcium carbonate shells or skeletons are negatively impacted by increasing co2 levels and decreasing ph in seawater.

the dependant variable is spilled water

the independent is the heat
