Could someone give me the steps to converting using the metric system scientific notation? For example, how would I convert 2.2 x 10^2 cm to km? Thanks ( I try Google but they only teach how to convert it when it not in scientific notations form)
2.2E2 cm x (1 m/100 cm) x (1 km/1000m) = 2E-3 km.
in 4.68 mg boron ther are how mant of the following: grams
moles
atoms
Sure! I'd be happy to help you with that.
To convert a measurement from one unit to another using scientific notation, you need to follow a few steps. Let's convert 2.2 x 10^2 cm to km.
Step 1: Determine the conversion factor
First, you need to find out how many centimeters are in one kilometer. To do this, you can use the fact that 1 kilometer is equal to 10^5 centimeters. This is because the prefix "kilo-" in the metric system denotes a factor of 10^3, and 1 kilometer is equal to 10^3 meters, and 1 meter is equal to 100 centimeters.
Step 2: Multiply by the conversion factor
Next, you need to multiply the given value by the conversion factor. In this case, you want to convert from centimeters to kilometers, so you need to divide by the conversion factor since the conversion factor is larger than 1.
2.2 x 10^2 cm * (1 km / 10^5 cm)
Step 3: Simplify the expression
To simplify, you can cancel out the common unit, which is "cm". This leaves us with:
2.2 x (1 km / 10^5)
Step 4: Multiply the numbers and simplify the power of 10
Now, you can multiply the numbers together and simplify the power of 10:
2.2 * 10^(-3) km
Step 5: Final answer
The final answer is 2.2 x 10^(-3) km. This means that 2.2 x 10^2 centimeters is equivalent to 2.2 x 10^(-3) kilometers.
I hope this helps! Let me know if you have any other questions.
