How many grams are 2.7x10-^4 grams
andrew-mc [135]

Answer:

0,00027 grams!

Step-by-step explanation:

This is a scientific notation problem.

When a number is followed by a 10^{-1}, it means that said number has one zero at the beginning.

In this case, the number is followed by 10^{-4}, so that means that 2.7 has four zeros at the beginning. So, 2.7x10^{-4} grams is equal to 0,00027 grams! (always the comma goes after the first zero).
