A half mole of oxygen contains approximately 3.01 x 10^23 oxygen atoms. This is because one mole of any substance contains Avogadro's number of atoms or molecules, which is 6.022 x 10^23. So, half a mole would contain half of that amount.
molicules=3(6.02*10^23) =18.06*10^23 atoms=1*18.06*10^23 =18.06*10^23
Yes - IF by 1023 you mean 10 to the 23 power.
1.8x10^20 / 6.022 x 10^23 = 2.99 x 10^(-4) = .000299 moles Also rounded could be 3.0 x 10^-4.
1 centimeter = 10 millimeters 23 centimeters = (23 times 10) = 230 millimeters
its 10,000,000,000,000,000,000 === 100 sextillion
8.45 x 10^23 = 845,000,000,000,000,000,000,000
10^-23 = 0.00000000000000000000001

23 000. This is standard form and should be written as: 23 x 10^2. (The ^ denotes an exponent.)
One hundred sextillion.
10² × 0.23 = 10 × 10 × 0.23 = 100 × 0.23 = 23 The quick way to do this is to note that the power of 10 is (positive) 2, so move the decimal point 2 places to the right → 10² × 0.23 = 23
