1.600ml of a mixture of O3 and O2 weighs 1g at NTP.calculate the volume of ozone in the mixture?
2.how many litres of liquid CCl4 (density=1.5g/cc) must be measured out to contain 1*10^25(or 10 raised to the power 25) CCl4 molecules?
3.which would be larger :an atomic mass unit based on the current standard or one based on the mass of Be - 9 atom set at exactly 9 amu?how?
4.the enzyme carbonic anhydrase catalysis the hydrogen of CO2. this reaction : CO2 + H2O ----} H2CO3 is involved in the transfer of CO2 from tissues to the lungs via the bloodstream . one enzyme molecule hydrates 10^6 molecules of CO2 per second.how many kg of CO2 are hydrated in one hour in one litre by 1*10^-6M enzyme?
5.22.4 litres of water vapour at NTP ,when condensed to water ,occupies an approximate volume of-?how?
6.is 1 g of water =1ml of water?give detail?
7.what is detonating gas?give the formula?
1. ASSUME A MIXTURE OF O2 AND O3 THE TOTAL VOLUME IS 0.6LITRES AND TOTAL WT IS 1gm AT NTP
LET US CONSIDER ''a'' LITRES AND ''b'' gm OF O3 IN THE MIXTURE THEREFORE THE VOLUME AND WT OF O3 PRESENT IN MIXTURE WOULD BE ''0.6-a'' litres and '' 1-b '' gm AT NTP
NOW MOLECULAR WT OF O2 AND O3 ARE 32 AND 48
AT STP AND NTP MOLES=VOLUME(LITRES)/22.4
ALSO MOLES = MASS/MOLECULAR MASS THEREFORE FOR O2 b/32=a/22.4...........................(1)
simillarly for O3 (1-b)/48=(0.6-a)/32.................(2)
SOLVING EQUATION (1) AND (2) GET THE VALUE OF ''a'' and ''b'' AND THEN GET YOUR REQUIRED ANSWER
.............................................................................................................................................................................................................................................................................................................................
2. NO. OF MOLECULES=NO. OF MOLES X AVAGADROS NO. AVAGADRO NO. IS 6.022 X 10^23
NO. OF MOLES = 10^25/6.022 X 10^23...........................(1)
NO. OF MOLES ALSO EQUAL TO= MASS / MOLECULAR MASS...............................(2) MOLECULAR MASS OF CCL4 IS 12+4 X 35.5=142+12=154
FROM USING (1) AND (2) GET THE VALUE OF MASS NOW DENSITY = 1.5gm/ml
DENSITY = MASS/VOLUME...................(3) YOU KNOW THE VALUE OF MASS AND DENSITY SUBSTITUTE THOSE VALUES IN EQUATION (3) AND GET YOUR ANSWER WHICH WILL BE ''ml''
..............................................................................................................................................................................................................................................................
3.
5. SINCE DENSITY OF WATER IS 1000KG/M^3 SO 22.4 L OF H2O GAS AT NTP MOLES=V(LITRES)/22.4 THE NO. OF MOLES @NTP IS 1 ALSO MOLES =WT/MOLECULAR MASS
MOLECULAR MASS OF H20 IS 18 THEREFORE WEIGHT OF H20 GAS WOULD BE 18 gm .SINCE H20 GAS IS CONVERTED TO H2O LIQUID THE MASS WOULD BE CONSERVED THEREFORE FORM DENSITY=MASS / VOLUME WE CAN CALCULATE VOLUME REMEMBER KEEP WT IN KG THE YOU WILL GET YOUR ANSWER IN M^3
6. SINCE WE KNOW DENSITY OF WATER IS 1000KG/M^3
1gm=(1/1000)KG AND 1ML=(1/1000000)M^3
BY SUBSTITUTING THE VALUES OF MASS AND VOLUME THE DENSITY COMES OUT TO BE 1000KG/M^3 AND HENCE 1gm=1ml
................................................................................................................................................................................................................................................................
4TH ANSWER IS TOO BIG AND HARD TO EXPLAIN ON P.C AND THE LAST ONE I DONT KNOW SORRY
AND IF YOU ARE SATISFIED PLZZZZZZZZZZZZ APPROVE THE ANSWER BY CLICKING YES BUTTON ....................
