How many grams of CuSO4 must be dissolved in 100 mL of total solution to create a 0.25 M solution of CuSO4?

A) 4 g

B) 25 g

C) 40 g

D) 159 g

A) 4 g

Explanation:

Data:

V  =100 mL = 0.1 L

M  = 0.25M

g = ?

Molarity

The moles are cleared from this equation:

Through the molecular weight, the grams of CuSO4 are calculated, knowing that the molecular weight of CuSO4 is 160 g/mol.

answer

fusion: the energy source of stars. the energy released from the collapse of the gas into a protostar causes the center of the protostar to become extremely hot. when the core is hot enough, nuclear fusion commences. fusion is the process where two hydrogen atoms combine to form a helium atom, releasing energy.

hope it

answer: i have one answer

acids are substances that ionize (break off) in an aqueous solution to produce hydrogen (h+) ions
