In order to change celcius to kelvin always add 73 to it leaving you with -195.93
<span>Igneous
rocks are those rocks that were formed through cooling and solidifying the
molten materials. The best example for igneous rock is solid volcanic java.
Lava are liquid that comes from a volcano, but once it is dried and solidify,
it becomes a rock and called igneous rock.
Another example is the granite and basalt. And according to research igneous
rock comes from the latin word ignis which means fire. Thus this says it all.
From a liquid becomes a rock.

Answer:
12.10 mol / 1 L
Explanation:
Molarity of a substance , is the number of moles present in a liter of solution .
M = n / V
M = molarity ( unit = mol / L or M )
V = volume of solution in liter ( unit = L ),
n = moles of solute ( unit = mol ),
Moles is denoted by given mass divided by the molecular mass ,
Hence ,
n = w / m
n = moles ,
w = given mass ,
m = molecular mass .
From the question ,
The data given is as follows -
w = 439 g
As , we known for HCl ,
m = 36.46 g/mol
V = 1 L
From the above data ,
Moles are given as -
n = w / m
n = 439 / 36.26 = 12.10 mol ,
Now , the molarity is given as ,
M = n / V
M = 12.10 mol / 1 L
M = 12.10 mol /L
