Calculate the volume in liters of a copper(II) sulfate solution that contains of copper(II) sulfate . Round your answer to significant digits.

Explanation:

Hello,

In this case, for the statement:

"Calculate the volume in liters of a 0.133mol/L copper (II) sulfate solution that contains 150.g of copper (II) sulfate (CuSO4). Be sure your answer has the correct number of significant digits"

We initially have the molar concentration as well as the mass of the copper (II) sulfate, therefore, we must first compute the moles of the given compound considering its molar mass (159.54 g/mol):

Then, considering the definition of molar concentration or molarity, we compute the required volume as follows:

Best regards.

given:

mass of na = 115 g

excess cl2

to determine:

mass of nacl produced

explanation:

given reaction is-

2na(s) + cl2(g) → 2nacl(s)

since cl2 is in excess, na will be the limiting reagent

as per the reaction stoichiometry na: nacl = 1: 1

i.e. moles of na reacted = moles of nacl formed

now, # moles of na = mass of na/atomic mass

                                  = 115 g/23 g.mol-1 = 5 moles

therefore, moles of nacl = 5

molar mass of nacl = 58 g/mol

mass of nacl = 5 moles * 58 g.mol-1 = 290 g

ans: amount of nacl produced = 290 g
