Answer:
Osmotic pressure is: 2,01 atm
Explanation:
Osmotic pressure is the minimum pressure that you needs to be apply to a solution to prevent the inward flow of its pure solvent across a semipermeable membrane. The formula of osmotic pressure is:
π = M×R×T
Where:
M is molar concentration of dissolved species (units of mol/L). <em>0,078M</em>
R is ideal gas constant (0.08206 L atm mol⁻¹ K⁻¹, ).
T is the temperature on the Kelvin scale. 41°C +273,15 = 314,15 K
Replacing you have:
π = 0,078M×0.08206 L atm mol⁻¹ K⁻¹×314,15 K
<em>π = 2,01 atm</em>

a. Group 2
b. Metal
a. The current highest numbered element known is Oganesson with an atomic number of 118 and it's the last period 7 element in group 18 (Noble gases). The hypothetical element number 120, would be the 2nd element in period 8 and the described electron configuration matches other group 2 elements such as Beryllium, Magnesium, Calcium, Strontium, Barium, and Radium.
b. The hypothetical element would be quite similar to the other group 2 elements which are the alkaline earth metals. The element would be expected to be a bit more reactive than Radium.
<span>When sugar or nacl is dissolved in water, the resulting solution is classified as homogeneous mixture.In the name homogeneous itself it refers to the meaning same,so it is referred as same proportions.For example, soda pops and lemonade, they can really be as solids, fluids, and gasses. Homogeneous mixture can likewise be a mix of these structures, as in a fluid gas mixture.</span>
