I also need help with 9.67nm=???km
and
2.3X10 to the -4g=????ng
Let see: nano is 10^-9
9.67*10^-9 m
2.3*10^-4g * 10^9ng/g=....
so if I did this right the answer would be -2.3x10^13 correct?
No. Two errors. Where did the minus sign come from? It shouldn't be there.
To multiply exponents we add them. -4 + 9 is not 13.
Certainly! Let's start with the first question:
To convert 9.67 nm to km, we need to perform a conversion using the appropriate conversion factor. In this case, we can use the fact that there are 1,000,000 nanometers (nm) in 1 kilometer (km).
So, to convert nm to km, we divide by 1,000,000:
9.67 nm ÷ 1,000,000 = 0.00000967 km
Therefore, 9.67 nanometers is equal to 0.00000967 kilometers.
Now, let's move on to the second question:
To convert 2.3 x 10^-4 grams (g) to nanograms (ng), we need to use the conversion factor that relates these two units. There are 1,000,000,000 nanograms (ng) in 1 gram (g).
We can start by multiplying 2.3 by 10^-4 to convert it to a decimal form:
2.3 x 10^-4 = 0.00023 grams
Now, to convert grams to nanograms, we multiply by 1,000,000,000:
0.00023 g x 1,000,000,000 ng/g = 230 ng
Therefore, 2.3 x 10^-4 grams is equal to 230 nanograms (ng).
