How do you know which unit of conversion factor must be in the denominator?

Answer 1

The unit that is used in the denominator is the one to cancels the unit that appears in a numerator.

Answer 2

I had to find this out for chemisty...an d i couldn't find the answer but i did find "a conversion factor is a fraction whose numerator and denominator are the same quantity expressed in different units." This may help but idk. If you have a white chemistry book with a yellow triangle then its on page 25.Hope this helps! ☺

Answer 3

The unit itself isn't important, because dimensional analysis works on the principle that multiplying a number by 1 leaves it unchanged. In this case, the conversion factor simply acts as the "1", or equivalent or what you're trying to convert but with different units. As a general way of thinking about this, the denominator unit should just be able to cancel itself out so that you get a new unit which would be the numerator. To do this, the conversion factor should be multiplied by the unit in its denominator. For example, if you know that a substance is 1 gram per cubic centimeter, you'll multiply it by a conversion factor which has grams in the denominator. When the units in a denominator multiply by the units of a numerator, they cancel out so your new answer is in cubic centimeters. You can also flip the conversion factors around to make it work, based on the values of the units that you know.

Answer 4

Assuming you are talking about stoichiometery a conversion factor is often a number with two units. For example a conversion factor could be Miles per hour (Miles/hour). If you had miles and needed to convert to hours you would multiply the miles by Hours/miles so that the miles would be canceled out (miles/miles = 1). Then your units left would be hours. Or vice versa. There are other factors like this in chemistry like grams/mol Mol/liter etc. To put it shortly the conversion factor denominator is always paired with the numerator.

Answer 5

Choose the unit to be in the denominator based on the desired unit in the final answer. Place it in the denominator so that it cancels out with the same unit in the numerator of the conversion factor, leaving the desired unit in the numerator.

Answer 6

They are equivalent.

Answer 7

because i no it right

Answer 8

I don’t know
