Answer:
a) ![\text{no of moles}=\frac{\text{given mass}}{\text{Molecular mass}}](https://tex.z-dn.net/?f=%5Ctext%7Bno%20of%20moles%7D%3D%5Cfrac%7B%5Ctext%7Bgiven%20mass%7D%7D%7B%5Ctext%7BMolecular%20mass%7D%7D)
![\text{no of moles of sucrose}=\frac{1.202g}{342g/mol}=0.0035moles](https://tex.z-dn.net/?f=%5Ctext%7Bno%20of%20moles%20of%20sucrose%7D%3D%5Cfrac%7B1.202g%7D%7B342g%2Fmol%7D%3D0.0035moles)
b) Moles of carbon in 1 mole of sucrose
= 12 moles
Moles of carbon in 0.0035 moles of sucrose ![C_{12}H_{22}O_{11}=\frac{12}{1}\times 0.0035=0.042moles](https://tex.z-dn.net/?f=C_%7B12%7DH_%7B22%7DO_%7B11%7D%3D%5Cfrac%7B12%7D%7B1%7D%5Ctimes%200.0035%3D0.042moles)
Moles of hydrogen in 1 mole of sucrose
= 22 moles
Moles of hydrogen in 0.0035 moles of sucrose ![C_{12}H_{22}O_{11}=\frac{22}{1}\times 0.0035=0.077moles](https://tex.z-dn.net/?f=C_%7B12%7DH_%7B22%7DO_%7B11%7D%3D%5Cfrac%7B22%7D%7B1%7D%5Ctimes%200.0035%3D0.077moles)
Moles of oxygen in 1 mole of sucrose
= 11 moles
Moles of oxygen in 0.0035 moles of sucrose ![C_{12}H_{22}O_{11}=\frac{11}{1}\times 0.0035=0.042moles](https://tex.z-dn.net/?f=C_%7B12%7DH_%7B22%7DO_%7B11%7D%3D%5Cfrac%7B11%7D%7B1%7D%5Ctimes%200.0035%3D0.042moles)
c) 1 mole of carbon contains ![=6.023\times 10^{23}atoms](https://tex.z-dn.net/?f=%3D6.023%5Ctimes%2010%5E%7B23%7Datoms)
0.042 moles of carbon contain ![=\frac{6.023\times 10^{23}}{1}\times 0.042=0.25\times 10^{23}atoms](https://tex.z-dn.net/?f=%3D%5Cfrac%7B6.023%5Ctimes%2010%5E%7B23%7D%7D%7B1%7D%5Ctimes%200.042%3D0.25%5Ctimes%2010%5E%7B23%7Datoms)
1 mole of hydrogen contains ![=6.023\times 10^{23}atoms](https://tex.z-dn.net/?f=%3D6.023%5Ctimes%2010%5E%7B23%7Datoms)
0.077 moles of hydrogen contain ![=\frac{6.023\times 10^{23}}{1}\times 0.077=0.46\times 10^{23}atoms](https://tex.z-dn.net/?f=%3D%5Cfrac%7B6.023%5Ctimes%2010%5E%7B23%7D%7D%7B1%7D%5Ctimes%200.077%3D0.46%5Ctimes%2010%5E%7B23%7Datoms)
1 mole of oxygen contains ![=6.023\times 10^{23}atoms](https://tex.z-dn.net/?f=%3D6.023%5Ctimes%2010%5E%7B23%7Datoms)
0.042 moles of oxygen contain ![=\frac{6.023\times 10^{23}}{1}\times 0.042=0.25\times 10^{23}atoms](https://tex.z-dn.net/?f=%3D%5Cfrac%7B6.023%5Ctimes%2010%5E%7B23%7D%7D%7B1%7D%5Ctimes%200.042%3D0.25%5Ctimes%2010%5E%7B23%7Datoms)
The Molarity will increase.
The request is characterized as knowing where things are and having the capacity to discover and utilize the things.
In a compound procedure, there is more issue, more entropy when the particles
1. warm up, increment in temperature. The atoms are more disorganized
2. get stirred up and must be isolated with exertion. Bedlam.
3. state changes, dissolves, vaporizes. The atoms are more turbulent
4. respond to frame a pack of various particles. More disorder
The answer is D :)
i remember this from like 7th grade
