write 63 ml in scientific notation

6.3E1 mL or 6.3 x 10^1 mL

To write any number in sci notation. place the decimal after the first digit, then count the places from the decimal to the end of the number and write "x 10^n" or "x 10^-n" where n stands for the number of places you counted. It is +n if you moved to the right; -n if you moved to the left.
6300 is 6.3E3 (6.3 x 10^3) and
0.000634 is 6.34E-4 (6.34 x 10^-4

To express 63 mL in scientific notation, we need to write it as a number between 1 and 10, multiplied by a power of 10. Here's how we can do it:

Step 1: Identify the non-zero digit
In 63 mL, the non-zero digit is 6.

Step 2: Determine the decimal place value
To determine the decimal place value, count the number of digits to the right of the non-zero digit. In this case, there are no digits to the right of 6.

Step 3: Write the number in scientific notation
The number 63 mL can be written as 6.3 × 10^1 mL in scientific notation. The exponent is 1 because there are no digits to the right of 6.

Therefore, 63 mL in scientific notation is 6.3 × 10^1 mL.
