Answer:
They are made up of electrons, neutrons and protons
Explanation:
The number is 25. The square root of 25 is 5 and 5x2 is 10 and then 10+5 is 15
Answer:
![V=14373.33\ \text{mm}^3](https://tex.z-dn.net/?f=V%3D14373.33%5C%20%5Ctext%7Bmm%7D%5E3)
Explanation:
It is given that,
The radius of the inflated balloon is 7 cm.
We need to find the volume of air inside the balloon in milliliters.
The balloon is in the shape of a sphere whose volume is given by :
![V=\dfrac{4}{3}\pi r^3\\\\\text{Put r = 7 cm}\\\\V=\dfrac{4}{3}\times \dfrac{22}{7}\times 7\times 7\times 7\\\\V=1437.33\ \text{cm}^3\\\\\text{We know that, 1 cm = 10 mm}\\\\\text{So},\\\\V=14373.33\ \text{mm}^3](https://tex.z-dn.net/?f=V%3D%5Cdfrac%7B4%7D%7B3%7D%5Cpi%20r%5E3%5C%5C%5C%5C%5Ctext%7BPut%20r%20%3D%207%20cm%7D%5C%5C%5C%5CV%3D%5Cdfrac%7B4%7D%7B3%7D%5Ctimes%20%5Cdfrac%7B22%7D%7B7%7D%5Ctimes%207%5Ctimes%207%5Ctimes%207%5C%5C%5C%5CV%3D1437.33%5C%20%5Ctext%7Bcm%7D%5E3%5C%5C%5C%5C%5Ctext%7BWe%20know%20that%2C%201%20cm%20%3D%2010%20mm%7D%5C%5C%5C%5C%5Ctext%7BSo%7D%2C%5C%5C%5C%5CV%3D14373.33%5C%20%5Ctext%7Bmm%7D%5E3)
Hence, the volume of the air inside the balloon is
.
C: 12.0107 g/mol ≅ 12.00 g/mol
H: 1.00784 g/mol ≅ 1.008 g/mol
O: 15.999 g/mol ≅ 16.00 g/mol
n(molar mass of CH2O)= 180
n.30=180
n=6
molecular formula: c6h12o6 glucose
