Answer:
Data:
mass of solute: 35g of NaCl
m.mass of solute: 58g/mol
volume of solution: 501mL
Molarity=?
Explanation:
501ml = 0.5dm3
M= g of solute/m.mass of solute*vol of solution
M= 35/58*0.5
M=1.20
Ch3sh is polar because it has polar bonds & the net dipole is nonzero
Answer:
The pressure of the gas will "increases by a factor of four."
Explanation:
The absolute zero in other words called as the absolute temperature. Whereas the absolute zero is the least possible temperature. In which nothing will remain cold and no heat can be released or present in the substance. When it is described in the figure it will be, –273.15 degrees Celsius on the Celsius scale. and 0 K on the Kelvin scale. This absolute temperature concept has been raised from the third law of the thermodynamics.
The concentration is 5 g/L.
Concentration = mass/volume = 10 g/2 L = 5 g/L
