Molar mass NaCl = 58.44 g/mol
number of moles:
mass NaCl / molar mass
145 / 58.44 => 2.4811 moles of NaCl
Volume = 3.45 L
Therefore :
M = moles / volume in liters:
M = 2.4811 / 3.45
M = 0.719 mol/L⁻¹
hope this helps!
Answer:
4200ml
Explanation:
Converting 3.1kg to g
3.1*1000= 3100g
Since density = mass/volume, then
volume = mass/ density
Therefore volume = 3100/0.74
= 4189.2ml
converting it to two significant figures
= 4200ml
the molar mass of Zn is 65
- number of mole(n)=reacting mass/molar mass
- n=45.2/65
- =0.70g/mol
2.the molar mass of Ag is 108
- 0.568=m/108
- then cross multiply
- m=0.568×108
- m=61.3g
