A ammonia as it has the least molar mass
Answer:
cd
Explanation:
image is formed due to reflected light rays and it is enlarged because image distance/ object distance = height of image/height of object
v>u so image is enlarged
Answer:
M = 1.18 mol/L
Explanation:
Moles is denoted by given mass divided by the molecular mass ,
Hence ,

n = moles ,
w = given mass ,
m = molecular mass .
From the information of the question ,
w = 78.3 g
As we known ,
molecular mass of
is 189.36 g/mol
m = 189.36 g/mol
moles can be calculated as -

n = 0.413 mol
MOLARITY -
Molarity of a substance , is the number of moles present in a liter of solution .

M = molarity ( unit = mol / L or M )
V = volume of solution in liter ( unit = L ),
n = moles of solute ( unit = mol ),
From the question ,.
V = 350 mL
Since , 1 mL = 10⁻³ L
V = 0.350 L
n = 0.413 mol
Molarity can be calculated as -

M = 1.18 mol/L
Is that supposed to say 200/2.00??
