Answer:
number of moles= 0.844 moles
Explanation:
Number of moles of Hydrogen atom = given mass / molar mass
given mass= 0.850 g
Molar mass= 1.007 g
number of moles= 0.850/1.007 = 0.844 moles
I dont know i don’t understand
Answer:
Explanation:
Number of moles of CuCl2 initially present = volume * molar concentration
= 0.134 * 8
= 1.072 mol.
Molar mass of CuCl2 = 63.5 + (2*35.5)
= 134.5 g/mol
Mass of CuCl2 = molar mass * number of moles
= 134.5 * 1.072
= 144.184 g
Mass of CuCl2 in 48 ml = 5.89 g in 48 ml
Volume = 5.89 * (48/144.184)
= 1.96 ml.
