% mass of a solution is the mass of the solute present per 100 g of solution. It can be calculated using the formula,
Mass of solute = 4.92 g
Mass of solvent, water = 347 g
Total mass of solution = 347 g + 4.92 g = 351.92 g
Mass % of the solute =
Therefore, the weight/weight % = 1.398 %
5.426 x molecules are there in a deep breath of air whose volume is 2. 35 L at body temperature 36 C and a pressure of 740 torr.
Explanation:
Data given:
volume V = 2.35 L
Temperature T = 36 Degrees or 273.15 + 36 = 309.15 K
pressure P = 740 torr OR 0.973 Atm
R = 0.08205 L atm / mole K
n (number of molecules of gas)= ?
The formula used will be
PV = nRT
Putting the value of given variables in above equation:
n =
=
= 0.0901 moles
According to Avagadro' s law that gases at equal volume, temperature and pressure contains same molecules.
number of molecules:
number of moles x avagadro number
0.0901 x 6.02 x
= 0.54 x
= 5.426 x molecules.
