Calculating the number of mole of COSO4 reacted
=mass/R.F.M
R.F.M of CUSO4 is 63.54+32+64=159.6
moles is therefore 200g/159.54=1.254moles
since reacting ratio is 1:1 ,moles of Cu is also 1.254moles
mass is therefore moles x R.F.M
1.254x63.54=79.6g(answer C)
Answer:
A
Explanation:
I am very good in science (please give brainliest)
A hot spring is formed as a result of conduction between magma and water.
Answer:
water in the flat plate is less so it takes lesser time to disappear
Explanation:
Answer:
The final volume of the copper (ii) sulfate solution = 93.6 mL
<em>Note: The question is incomplete. The complete question is given below:</em>
<em>A chemist must dilute 37.0 mL of 602. mM aqueous copper(II) sulfate (Cuso4) solution until the concentration falls to 238. mM. He'll do this by adding distilled water to the solution until it reaches a certain final volume. Calculate this final volume, in milliliters. Be sure your answer has the correct number of significant digits.</em>
Explanation:
Using the equation of dilution, C₁V₁ = C₂V₂
where C₁ = initial concentration
V₁ = initial volume
C₂ = final concentration
V₂ = final volume
For the aqueous solution of copper (ii) sulfate
C₁ = 602 mM; V₁ = 37.0 mL; C₂ = 238 mM; V₂ = ?
Making V₂ subject of formula
V₂ = C₁V₁/C₂
V₂ = (602 mM * 37.0 mL)/238 mM
V₂ = 93.6 mL
Therefore, the final volume of the copper (ii) sulfate solution = 93.6 mL
