Answer:
91.5g
Explanation:
the mass of a liquid is calculated by multiplying its volume by its density
mathematically
density = mass/volume
Therefore
mass = density x volume
1.83gm/l = mass/50ml
mass = 1.83 x 50
mass = 91.5g
The molecular mass of is:
2·1 + 1·32 + 4·16 = 98 g/mol
The amount of solute, expressed by mol, is:
The molar concentration definition is:
Doing the calculations:
