Add water to mixture to dissolve sugar then filter. sugared water will be the filtrate while the salt & iron fillings will be the residue. use magnet to attract iron fillings and remaining will be salt.
Answer:
0.29 mol/L
Explanation:
Its density is 1.029 g/ml so in a liter (1000 mL) there is 1029 g of solution, but only 5% is dextrose.
0.05x1029=51.45
So in a liter of D5W solution there is 51.45 g of dextrose.
Dextrose molar mass iss 180.156 g/mol, so in 51.45 g of dextrose there is
51.45/180.156=0.29 mol
In one liter of solution there is 0.29 mol of dextrose, so the molarity of such solution is 0.29 mol/L.
Answer & Explanation:
D orbitals begin filling with electrons after the orbital found in the 4s sublevel is filled. This occurs because the d sublevel is first found in the.
