Its very simple. Here the required Answer for you
molecules=25 .6.022.1023
16 [methane=CH4=16g]
= 4.704.1023
no. of moles = 25
16
=1.56 moles
no. of H atoms=4. 1.56 . 6.022. 1023
= 3.7577 .1023
no. of c atoms =1.56 . 6.022 .1023
=9.3943 .1023
molecules=25 .6.022.1023

mera first question ap btao sir pehle
Ask plz
what is the weight of one millimole of so2
Weight of 1 mole of any substance = Gram molecular mass of that substance.
So weight of 1 mole of SO2 = (1×32)+(2×16) g =62 g.
Also we know milli refers to the fraction 1/1000.
Hence weight of 1 millimole of SO2
= (Weight of 1 mole of SO2)/1000
=64 g/1000
=0.064 g.
So weight of 1 mole of SO2 = (1×32)+(2×16) g =62 g.
Also we know milli refers to the fraction 1/1000.
Hence weight of 1 millimole of SO2
= (Weight of 1 mole of SO2)/1000
=64 g/1000
=0.064 g.
answer kya hai iska
0.064g simple
