i m a student of class 9 . The 2nd chepter of our chemistry book is chemical combinations.i can't understand this chepter if u have any solution then tell me
To calculate the mass of 2.2 x 10^9 CO2 molecules, you would first determine the molar mass of one CO2 molecule (44.01 g/mol). Then, multiply the molar mass by the number of molecules given (2.2 x 10^9) to find the mass. The mass of 2.2 x 10^9 CO2 molecules would be approximately 96.82 grams.
To find the number of moles of THC in 27 nanograms, you first need to convert nanograms to grams (1 ng = 1e-9 g). Then use the molar mass of THC (C21H30O2) to convert grams to moles. Next, you can calculate the number of molecules using Avogadro's number (6.022e23 molecules/mol). The exact calculations would be: (27e-9 g THC) / (314.46 g/mol THC) = 8.59e-11 moles, and (8.59e-11 moles) * (6.022e23 molecules/mol) = 5.17e13 molecules.
Since the molecular mass of water is about 18 and the molecular mass of C12H22O11 is about 342, it takes considerably more molecules of water to make up 9 g than molecules of C12H22O11 to get the same mass.
9 g of water contains approximately 3.01 x 10^23 molecules. The gas that contains the same number of molecules as 9 g of water is Avogadro's gas constant, which is about 22.4 liters per mole at standard temperature and pressure.

Each molecule of carbon dioxide (CO2) contains one carbon atom and two oxygen atoms, totaling three atoms per molecule. Therefore, in 3 molecules of CO2, there are 3 carbon atoms and 6 oxygen atoms, resulting in a total of 9 atoms.

18+x=27 calculate and your answer should be 9.
If you replace some number for "p", you can calculate the sum. Otherwise, just write it as "p+9" - you can't simplify this.If you replace some number for "p", you can calculate the sum.

(4^3)-(3^3)-(9+1)
To find the base number when the number is 729 and the exponent is 3, you need to calculate the cube root of 729. The cube root of 729 is 9, since (9^3 = 729). Therefore, the base number is 9.
Takeaway the highest number from the lowest number For example: 2,2,3,4,5,9,11 The range would be 11-2=9
You need more than one number to calculate a standard deviation, so 9 does not have a standard deviation.
