Answer: the answer is d.).
Explanation:
Answer:
The volume of the solution is 133 ml
Explanation:
Having a 0.250 molar solution means 0.250 moles in 1000 ml of solution (1 liter)
We calculate the weight of 1 mole of CuNO3, and use 3 simple rules for calculations:
CuNo3---> Weight of 1 mole= 63, 546g+ 14, 0067g+ 3X 15, 9999g= 125, 55g/mol
1 mol----125, 55g
0,250mol---X= (0,250molx 125,55g)/1mol= 31,3 g
31,3g----1000ml
4,16g---x= (4,16gx1000ml)/31,3g = 133ml
