The chemical formula for carbon dioxide is CO2, hope this helps.
Im pretty sure it weight because when we are on different plants with a different amount of gravitational pull our weight changes
hope this helps :)
The careers in chemistry should be closely related to working with chemical substances and the methods involved in experiments. Thus, the answers are finds practical applications information chemist and<span> market research R&D.</span>
Ans: Elements in the same period have the same number of electron shells.
213034 torr is the osmotic pressure.
Explanation:
osmotic pressure is calculated by the formula:
osmotic pressure= iCrT
where i= no. of solute
c= concentration in mol/litre
R= Universal Gas constant
T = temp
It is given that solution is 3% which is 3gms in 100 ml.
let us calculate the concentration in moles/litre
3gm/100ml*1000ml/1L*1mol NaCl/55.84g NaCl
= 5.372 gm/litre
Putting the values in the formula, Temp in Kelvin 318.5K
osmotic pressure= 2*5.372*0.083 * 318.5 Gas constant 0.083
= 284.023 bar or 213018 torr. c= 5.372 moles/L
i=2 for NaCl
