15 lut 2018 · Answer link. A conversion factor is a factor that is used to change between units, and therefore gives the relationship between two units. For example, a common conversion factor would be 1 \ "km" = 1000 \ "m" or 1 \ "minute" = 60 \ "seconds" So, when we want to convert between two certain units, we can find their conversion factor (like 1,12 ...
20 cze 2017 · Use dimensional analysis (a.k.a. factor-label method). Given: (x" km")/"h" Multiply by the conversion factor (1000" m")/(1" km"): (xcancel(" km"))/"h"xx(1000" m ...
1 gru 2016 · See the explanation. The equality between grams and kilograms is "1000 g=1 kg". This gives two equivalent fractions, also called conversion factors. They are "1000 g"/"1 kg" and "1 kg"/"1000 g"=1". Equivalent fractions or conversion factors always equal 1. When converting grams to kilograms, you would use the second conversion factor. This will cancel grams and leave you with kilograms ...
12 mar 2018 · 2.303 is a conversion factor from natural log to log10. Log is commonly represented in base-10 whereas natural log or Ln is represented in base e. Now e has a value of 2.71828. So e raised to the power of 2.303 equals 10 ie 2.71828 raised to the power of 2.303 equals 10 and hence ln 10 equals 2.303 and so we multiply 2.303 to convert ln to log.
17 cze 2018 · A conversion factor is a multiplying fraction that is alway equal to one. You use the conversion factor that relates grams and pounds. You may know that. 1 kg = 2.2 lb. (It's actually 2.204 62 kg, but we can use the approximate number here.) If you divide both sides of the equation by 2.2 lb, we get. 1 kg 2.2 lb = 2.2 lb 2.2 lb = 1.
28 wrz 2014 · 1 Answer. You create a conversion factor from the molar mass and use it in your calculations. Example 1. Convert 25.0 g of water to moles of water. We know that 1 mol H₂O = 180.2 g H₂O. We can use this to create the conversion factors 1 mol H2O 18.02 g H2O and 18.02 g H2O 1 mol H2O. We choose the one that gives us the correct units for the ...
Solution. Step 1: Convert all masses into moles. 1.20g Al × 1 mol Al 26.98g Al = 0.044 48 mol Al. 2.40g I₂ × 1 mol I2 253.8g I₂ = 0.009 456 mol I2. Step 2: Calculate the molar ratios. To calculate the molar ratios, you put the moles of one reactant over the moles of the other reactant.
Certain systems, such as the SI system of units, have different units for describing the same features, such as the meter and millimeter, which are both units of distance. If a measurement is given in one unit, it can be converted into another unit describing the same property, such as length. A conversion factor can be used, such as a meter being 1000 times more than a millimeter ...
27 kwi 2015 · Apr 27, 2015. The conversion factor that is always used in stoichiometry problems is the mole to mole ratio for elements or compounds in the balanced equation. Another conversion factor that is commonly used in stoichiometry is the molar mass, or g/mol. For example, the reaction between hydrogen and oxygen gas to form water can be represented ...
1 inch : 2.54 cm as 1 16 inches : x cm. and then solve for x: x = 2.54(1 16) = 0.15875 cm. Or you could use a conversion factor: 1 16 inch x 2.54 1. which gives you the same answer of 0.15875 cm. Just as a little tip when using conversion factors, when you convert to a smaller quantity, it will always go on the top of your factor, and when you ...
