Find product and write answer in scientific notation
(3 x 10^6). * (2 * 10^12)
I got
.6 x 10 ^19
Is this right?

I believe it is 6 x 10^18. You multiply the 3 x 2. Then add the exponents together = 6 + 12.

If you mixed 25.00g of salt in 100.00mL of water and it all dissolved, what would the concentration be in g/mL?

3x^2(2x2)
I don't know the answer can you help me?
