One hundred sextillion.
23 000. This is standard form and should be written as: 23 x 10^2. (The ^ denotes an exponent.)
23 = 8
723 = 27,368,747,340,080,916,343
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
One hundred sextillion.
8.45 x 10^23 = 845,000,000,000,000,000,000,000

2.6 * 6.022 * 10^23 atoms Explanation- 1 mol of anything has 6.022 * 10^23 units. So 2.6 mol has 2.6 times this number. Also Cu is monoatomic Note: * means multiplied; ^ means raised to the power
The result is 3.0066445 x 1046
n to the power of 9
It is 6.02 (times) 10 to the power of 23
